+In B shell, edit .bashrc file in your home directory, add the following line
+	export PATH=/python-dir/bin:$PATH
+In C shell, edit .cshrc file in your home directory, add the following line
+	setenv PATH /python-dir/bin:$PATH
+To make the changes effective, source the .bashrc file or .cshrc file
+	$ source .bashrc
+
+Now check python version again. Python 2.7 should have been installed and set to be the default python. 
+
+2. Install third party packages
+(1) download pysam and biopython
+	$ wget https://pysam.googlecode.com/files/pysam-0.6.tar.gz
+	$ wget http://biopython.org/DIST/biopython-1.60.tar.gz
+(2) unzip files 
+	$ tar zxfv biopython-1.60.tar.gz
+	$ tar zxfv pysam-0.6.tar.gz
+(3) configure / make
+	$ cd biopython-1.60
+	$ python setup.py install
+	$ cd pysam-0.6
+	$ python setup.py install
+(4) test
+You may leave the directories and test your package installations.
+	$ cd 
+	$ python
+This brings you to the python interactive interface. Import the two packages, if no error occurs, your packages have been successfully installed. Otherwise, consult your administrator or someone with experiences with python. 
+
+>>> import pysam
+>>> import Bio
+
+3. Install pyPRADA
+pyPRADA has been pre-compiled, thus does not require configure/make steps. To make it more convenient, we recommend to add its path to system path. 
+First, unzip the package to the location you prefer. To add the path to system, see step 1.(4)
+
+4. Test pyRADA
+To test pyPRADA, type the following command in your terminal. It will return a user manual for prada-fusion module. 
+
+	$ prada-fusion
+
+5. Help
+For assistance or bug report, contact Siyuan Zheng (szheng2@mdanderson.org) or Rahul Vegesna (RVegesna@mdanderson.org).

+\tprada-preprocess-bi -conf xx.txt -inputdir .. -sample XX -tag TCGA-XX -platform illumina -step 1_1 -intermediate no -pbs xxx -outdir ... -submit no
+\t**Parameters**:
+\t-h		print help message
+\t-step_info	print complete steps curated in the module.
+\t-inputdir	the dir where the input bam or fastq can be found.
+\t-sample		input sample name. PRADA searches for sample.bam or sample.end1.fastq/sample.end2.fastq, etc, depending on the 
+\t		initiating step number. See step_info for more information. 
+\t-conf		config file for references and parameters. Default is conf.txt in py-PRADA installation folder. 
+\t-tag		a tag to describe the sample, likely sample ID, such as TCGA-LGG-01; no default.
+\t-platform	only illumina at present (default). 
+\t-step		values: 1_1/2,2_e1/2_1/2/3/4,3_e1/2_1/2,4_1/2,5,6_1/2,7,8; example 2_e1_1; no default.
+\t-outdir		output dir. Default is the directory where the input bam is. 
+\t-pbs		name for output pbs file and log file. Default (time-stamp) is used if no input. 
+\t-intermediate	values:yes/no; if intermediate files should be kept. Default is not. 
+\t-submit		if submit the job to HPC, default is no. If yes, ppn is set to 12.
+\t-v		print version information.

+TEST EXAMPLES
+To run these examples, set your PBS queue to short, walltime to 1:00:00 and ppn to 2
+For the following exmaples, I assume the current location is the PRADA directory
+Please use "tar xzvf U87_chr17p13.2.end1.fastq.tar.gz" to unzip the fastq file.
+Please see manual how to add PRADA to system path. 
+
+1. Run PRADA from BAM
+./prada-preprocess-bi -inputdir testdata -sample U87_chr17p13.2 -tag U87 -step 1_1 -pbs frombam -outdir testdata/test1 -submit yes

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+Simply type `make' to compile and copy the resulting executable `bwa'
+anywhere you want. You may also like to copy `solid2fastq.pl' and
+`qualfa2fq.pl' for format conversion.
+
+On 32-bit system, you should compile bwa with `make CFLAGS=-O2'.

+Beta Release 0.5.7 (1 March, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This release only has an effect on paired-end data with fat insert-size
+distribution. Users are still recommended to update as the new release
+improves the robustness to poor data.
+
+ * The fix for `weird pairing' was not working in version 0.5.6, pointed
+   out by Carol Scott. It should work now.
+
+ * Optionally output to a normal file rather than to stdout (by Tim
+   Fennel).
+
+(0.5.7: 1 March 2010, r1310)
+
+
+
+Beta Release 0.5.6 (10 Feburary, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes in bwa-short:
+
+ * Report multiple hits in the SAM format at a new tag XA encoded as:
+   (chr,pos,CIGAR,NM;)*. By default, if a paired or single-end read has
+   4 or fewer hits, they will all be reported; if a read in a anomalous
+   pair has 11 or fewer hits, all of them will be reported.
+
+ * Perform Smith-Waterman alignment also for anomalous read pairs when
+   both ends have quality higher than 17. This reduces false positives
+   for some SV discovery algorithms.
+
+ * Do not report "weird pairing" when the insert size distribution is
+   too fat or has a mean close to zero.
+
+ * If a read is bridging two adjacent chromsomes, flag it as unmapped.
+
+ * Fixed a small but long existing memory leak in paired-end mapping.
+
+ * Multiple bug fixes in SOLiD mapping: a) quality "-1" can be correctly
+   parsed by solid2fastq.pl; b) truncated quality string is resolved; c)
+   SOLiD read mapped to the reverse strand is complemented.
+
+ * Bwa now calculates skewness and kurtosis of the insert size
+   distribution.
+
+ * Deploy a Bayesian method to estimate the maximum distance for a read
+   pair considered to be paired properly. The method is proposed by
+   Gerton Lunter, but bwa only implements a simplified version.
+
+ * Export more functions for Java bindings, by Matt Hanna (See:
+   http://www.broadinstitute.org/gsa/wiki/index.php/Sting_BWA/C_bindings)
+
+ * Abstract bwa CIGAR for further extension, by Rodrigo Goya.
+
+(0.5.6: 10 Feburary 2010, r1303)
+
+
+
+Beta Release 0.5.5 (10 November, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is a bug fix release:
+
+ * Fixed a serious bug/typo in aln which does not occur given short
+   reads, but will lead to segfault for >500bp reads. Of course, the aln
+   command is not recommended for reads longer than 200bp, but this is a
+   bug anyway.
+
+ * Fixed a minor bug/typo which leads to incorrect single-end mapping
+   quality when one end is moved to meet the mate-pair requirement.
+
+ * Fixed a bug in samse for mapping in the color space. This bug is
+   caused by quality filtration added since 0.5.1.
+
+(0.5.5: 10 November 2009, r1273)
+
+
+
+Beta Release 0.5.4 (9 October, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Since this version, the default seed length used in the "aln" command is
+changed to 32.
+
+Notable changes in bwa-short:
+
+ * Added a new tag "XC:i" which gives the length of clipped reads.
+
+ * In sampe, skip alignments in case of a bug in the Smith-Waterman
+   alignment module.
+
+ * In sampe, fixed a bug in pairing when the read sequence is identical
+   to its reverse complement.
+
+ * In sampe, optionally preload the entire FM-index into memory to
+   reduce disk operations.
+
+Notable changes in dBWT-SW/BWA-SW:
+
+ * Changed name dBWT-SW to BWA-SW.
+
+ * Optionally use "hard clipping" in the SAM output.
+
+(0.5.4: 9 October 2009, r1245)
+
+
+
+Beta Release 0.5.3 (15 September, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Fixed a critical bug in bwa-short: reads mapped to the reverse strand
+are not complemented.
+
+(0.5.3: 15 September 2009, r1225)
+
+
+
+Beta Release 0.5.2 (13 September, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes in bwa-short:
+
+ * Optionally trim reads before alignment. See the manual page on `aln
+   -q' for detailed description.
+
+ * Fixed a bug in calculating the NM tag for a gapped alignment.
+
+ * Fixed a bug given a mixture of reads with some longer than the seed
+   length and some shorter.
+
+ * Print SAM header.
+
+Notable changes in dBWT-SW:
+
+ * Changed the default value of -T to 30. As a result, the accuracy is a
+   little higher for short reads at the cost of speed.
+
+(0.5.2: 13 September 2009, r1223)
+
+
+
+Beta Release 0.5.1 (2 September, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes in the short read alignment component:
+
+ * Fixed a bug in samse: do not write mate coordinates.
+
+Notable changes in dBWT-SW:
+
+ * Randomly choose one alignment if the read is a repetitive.
+
+ * Fixed a flaw when a read is mapped across two adjacent reference
+   sequences. However, wrong alignment reports may still occur rarely in
+   this case.
+
+ * Changed the default band width to 50. The speed is slower due to this
+   change.
+
+ * Improved the mapping quality a little given long query sequences.
+
+(0.5.1: 2 September 2009, r1209)
+
+
+
+Beta Release 0.5.0 (20 August, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This release implements a novel algorithm, dBWT-SW, specifically
+designed for long reads. It is 10-50 times faster than SSAHA2, depending
+on the characteristics of the input data, and achieves comparable
+alignment accuracy while allowing chimera detection. In comparison to
+BLAT, dBWT-SW is several times faster and much more accurate especially
+when the error rate is high. Please read the manual page for more
+information.
+
+The dBWT-SW algorithm is kind of developed for future sequencing
+technologies which produce much longer reads with a little higher error
+rate. It is still at its early development stage. Some features are
+missing and it may be buggy although I have evaluated on several
+simulated and real data sets. But following the "release early"
+paradigm, I would like the users to try it first.
+
+Other notable changes in BWA are:
+
+ * Fixed a rare bug in the Smith-Waterman alignment module.
+
+ * Fixed a rare bug about the wrong alignment coordinate when a read is
+   poorly aligned.
+
+ * Fixed a bug in generating the "mate-unmap" SAM tag when both ends in
+   a pair are unmapped.
+
+(0.5.0: 20 August 2009, r1200)
+
+
+
+Beta Release 0.4.9 (19 May, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Interestingly, the integer overflow bug claimed to be fixed in 0.4.7 has
+not in fact. Now I have fixed the bug. Sorry for this and thank Quan
+Long for pointing out the bug (again).
+
+(0.4.9: 19 May 2009, r1075)
+
+
+
+Beta Release 0.4.8 (18 May, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One change to "aln -R". Now by default, if there are no more than `-R'
+equally best hits, bwa will search for suboptimal hits. This change
+affects the ability in finding SNPs in segmental duplications.
+
+I have not tested this option thoroughly, but this simple change is less
+likely to cause new bugs. Hope I am right.
+
+(0.4.8: 18 May 2009, r1073)
+
+
+
+Beta Release 0.4.7 (12 May, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes:
+
+ * Output SM (single-end mapping quality) and AM (smaller mapping
+   quality among the two ends) tag from sam output.
+
+ * Improved the functionality of stdsw.
+
+ * Made the XN tag more accurate.
+
+ * Fixed a very rare segfault caused by integer overflow.
+
+ * Improve the insert size estimation.
+
+ * Fixed compiling errors for some Linux systems.
+
+(0.4.7: 12 May 2009, r1066)
+
+
+
+Beta Release 0.4.6 (9 March, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This release improves the SOLiD support. First, a script for converting
+SOLiD raw data is provided. This script is adapted from solid2fastq.pl
+in the MAQ package. Second, a nucleotide reference file can be directly
+used with `bwa index'. Third, SOLiD paired-end support is
+completed. Fourth, color-space reads will be converted to nucleotides
+when SAM output is generated. Color errors are corrected in this
+process. Please note that like MAQ, BWA cannot make use of the primer
+base and the first color.
+
+In addition, the calculation of mapping quality is also improved a
+little bit, although end-users may barely observe the difference.
+
+(0.4.6: 9 March 2009, r915)
+
+
+
+Beta Release 0.4.5 (18 Feburary, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Not much happened, but I think it would be good to let the users use the
+latest version.
+
+Notable changes (Thank Bob Handsaker for catching the two bugs):
+
+ * Improved bounary check. Previous version may still give incorrect
+   alignment coordinates in rare cases.
+
+ * Fixed a bug in SW alignment when no residue matches. This only
+   affects the `sampe' command.
+
+ * Robustly estimate insert size without setting the maximum on the
+   command line. Since this release `sampe -a' only has an effect if
+   there are not enough good pairs to infer the insert size
+   distribution.
+
+ * Reduced false PE alignments a little bit by using the inferred insert
+   size distribution. This fix may be more important for long insert
+   size libraries.
+
+(0.4.5: 18 Feburary 2009, r829)
+
+
+
+Beta Release 0.4.4 (15 Feburary, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is mainly a bug fix release. Notable changes are:
+
+ * Imposed boundary check for extracting subsequence from the
+   genome. Previously this causes memory problem in rare cases.
+
+ * Fixed a bug in failing to find whether an alignment overlapping with
+   N on the genome.
+
+ * Changed MD tag to meet the latest SAM specification.
+
+(0.4.4: 15 Feburary 2009, r815)
+
+
+
+Beta Release 0.4.3 (22 January, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes:
+
+ * Treat an ambiguous base N as a mismatch. Previous versions will not
+   map reads containing any N.
+
+ * Automatically choose the maximum allowed number of differences. This
+   is important when reads of different lengths are mixed together.
+
+ * Print mate coordinate if only one end is unmapped.
+
+ * Generate MD tag. This tag encodes the mismatching positions and the
+   reference bases at these positions. Deletions from the reference will
+   also be printed.
+
+ * Optionally dump multiple hits from samse, in another concise format
+   rather than SAM.
+
+ * Optionally disable iterative search. This is VERY SLOOOOW, though.
+
+ * Fixed a bug in generate SAM.
+
+(0.4.3: 22 January 2009, r787)
+
+
+
+Beta Release 0.4.2 (9 January, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Aaron Quinlan found a bug in the indexer: the bwa indexer segfaults if
+there are no comment texts in the FASTA header. This is a critical
+bug. Nothing else was changed.
+
+(0.4.2: 9 January 2009, r769)
+
+
+
+Beta Release 0.4.1 (7 January, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I am sorry for the quick updates these days. I like to set a milestone
+for BWA and this release seems to be. For paired end reads, BWA also
+does Smith-Waterman alignment for an unmapped read whose mate can be
+mapped confidently. With this strategy BWA achieves similar accuracy to
+maq. Benchmark is also updated accordingly.
+
+(0.4.1: 7 January 2009, r760)
+
+
+
+Beta Release 0.4.0 (6 January, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In comparison to the release two days ago, this release is mainly tuned
+for performance with some tricks I learnt from Bowtie. However, as the
+indexing format has also been changed, I have to increase the version
+number to 0.4.0 to emphasize that *DATABASE MUST BE RE-INDEXED* with
+`bwa index'.
+
+ * Improved the speed by about 20%.
+
+ * Added multi-threading to `bwa aln'.
+
+(0.4.0: 6 January 2009, r756)
+
+
+
+Beta Release 0.3.0 (4 January, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ * Added paired-end support by separating SA calculation and alignment
+   output.
+
+ * Added SAM output.
+
+ * Added evaluation to the documentation.
+
+(0.3.0: 4 January 2009, r741)
+
+
+
+Beta Release 0.2.0 (15 Augusst, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ * Take the subsequence at the 5'-end as seed. Seeding strategy greatly
+   improves the speed for long reads, at the cost of missing a few true
+   hits that contain many differences in the seed. Seeding also increase
+   the memory by 800MB.
+
+ * Fixed a bug which may miss some gapped alignments. Fixing the bug
+   also slows the speed a little.
+
+(0.2.0: 15 August 2008, r428)
+
+
+
+Beta Release 0.1.6 (08 Augusst, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ * Give accurate CIGAR string.
+
+ * Add a simple interface to SW/NW alignment
+
+(0.1.6: 08 August 2008, r414)
+
+
+
+Beta Release 0.1.5 (27 July, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ * Improve the speed. This version is expected to give the same results.
+
+(0.1.5: 27 July 2008, r400)
+
+
+
+Beta Release 0.1.4 (22 July, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ * Fixed a bug which may cause missing gapped alignments.
+
+ * More clearly define what alignments can be found by BWA (See
+   manual). Now BWA runs a little slower because it will visit more
+   potential gapped alignments.
+
+ * A bit code clean up.
+
+(0.1.4: 22 July 2008, r387)
+
+
+
+Beta Release 0.1.3 (21 July, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Improve the speed with some tricks on retrieving occurences. The results
+should be exactly the same as that of 0.1.2.
+
+(0.1.3: 21 July 2008, r382)
+
+
+
+Beta Release 0.1.2 (17 July, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Support gapped alignment. Codes for ungapped alignment has been removed.
+
+(0.1.2: 17 July 2008, r371)
+
+
+
+Beta Release 0.1.1 (03 June, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the first release of BWA, Burrows-Wheeler Alignment tool. Please
+read man page for more information about this software.
+

+
+.SH DESCRIPTION
+.PP
+BWA is a fast light-weighted tool that aligns relatively short sequences
+(queries) to a sequence database (targe), such as the human reference
+genome. It implements two different algorithms, both based on
+Burrows-Wheeler Transform (BWT). The first algorithm is designed for
+short queries up to ~200bp with low error rate (<3%). It does gapped
+global alignment w.r.t. queries, supports paired-end reads, and is one
+of the fastest short read alignment algorithms to date while also
+visiting suboptimal hits. The second algorithm, BWA-SW, is designed for
+long reads with more errors. It performs heuristic Smith-Waterman-like
+alignment to find high-scoring local hits (and thus chimera). On
+low-error short queries, BWA-SW is slower and less accurate than the
+first algorithm, but on long queries, it is better.
+.PP
+For both algorithms, the database file in the FASTA format must be
+first indexed with the
+.B `index'
+command, which typically takes a few hours. The first algorithm is
+implemented via the
+.B `aln'
+command, which finds the suffix array (SA) coordinates of good hits of
+each individual read, and the
+.B `samse/sampe'
+command, which converts SA coordinates to chromosomal coordinate and
+pairs reads (for `sampe'). The second algorithm is invoked by the
+.B `dbtwsw'
+command. It works for single-end reads only.
+
+.SH COMMANDS AND OPTIONS
+.TP
+.B index
+bwa index [-p prefix] [-a algoType] [-c] <in.db.fasta>
+
+Index database sequences in the FASTA format.
+
+.B OPTIONS:
+.RS
+.TP 10
+.B -c
+Build color-space index. The input fast should be in nucleotide space.
+.TP
+.B -p STR
+Prefix of the output database [same as db filename]
+.TP
+.B -a STR
+Algorithm for constructing BWT index. Available options are:
+.RS
+.TP
+.B is
+IS linear-time algorithm for constructing suffix array. It requires
+5.37N memory where N is the size of the database. IS is moderately fast,
+but does not work with database larger than 2GB. IS is the default
+algorithm due to its simplicity. The current codes for IS algorithm are
+reimplemented by Yuta Mori.
+.TP
+.B bwtsw
+Algorithm implemented in BWT-SW. This method works with the whole human
+genome, but it does not work with database smaller than 10MB and it is
+usually slower than IS.

+[-O gapOsc] [-E gapEsc] [-q trimQual] <in.db.fasta> <in.query.fq> >
+<out.sai>
+
+Find the SA coordinates of the input reads. Maximum
+.I maxSeedDiff
+differences are allowed in the first
+.I seedLen
+subsequence and maximum
+.I maxDiff
+differences are allowed in the whole sequence.
+
+.B OPTIONS:
+.RS
+.TP 10
+.B -n NUM
+Maximum edit distance if the value is INT, or the fraction of missing
+alignments given 2% uniform base error rate if FLOAT. In the latter
+case, the maximum edit distance is automatically chosen for different
+read lengths. [0.04]
+.TP
+.B -o INT
+Maximum number of gap opens [1]
+.TP
+.B -e INT
+Maximum number of gap extensions, -1 for k-difference mode (disallowing
+long gaps) [-1]
+.TP
+.B -d INT
+Disallow a long deletion within INT bp towards the 3'-end [16]
+.TP
+.B -i INT
+Disallow an indel within INT bp towards the ends [5]
+.TP
+.B -l INT
+Take the first INT subsequence as seed. If INT is larger than the query
+sequence, seeding will be disabled. For long reads, this option is
+typically ranged from 25 to 35 for `-k 2'. [inf]
+.TP
+.B -k INT
+Maximum edit distance in the seed [2]
+.TP
+.B -t INT
+Number of threads (multi-threading mode) [1]
+.TP
+.B -M INT
+Mismatch penalty. BWA will not search for suboptimal hits with a score
+lower than (bestScore-misMsc). [3]
+.TP
+.B -O INT
+Gap open penalty [11]
+.TP
+.B -E INT
+Gap extension penalty [4]
+.TP
+.B -R INT
+Proceed with suboptimal alignments if there are no more than INT equally
+best hits. This option only affects paired-end mapping. Increasing this
+threshold helps to improve the pairing accuracy at the cost of speed,
+especially for short reads (~32bp).
+.TP
+.B -c
+Reverse query but not complement it, which is required for alignment in
+the color space.
+.TP
+.B -N
+Disable iterative search. All hits with no more than
+.I maxDiff
+differences will be found. This mode is much slower than the default.
+.TP
+.B -q INT
+Parameter for read trimming. BWA trims a read down to
+argmax_x{\\sum_{i=x+1}^l(INT-q_i)} if q_l<INT where l is the original
+read length. [0]
+.RE
+
+.TP
+.B samse
+bwa samse [-n maxOcc] <in.db.fasta> <in.sai> <in.fq> > <out.sam>
+
+Generate alignments in the SAM format given single-end reads. Repetitive
+hits will be randomly chosen.
+
+.B OPTIONS:
+.RS
+.TP 10
+.B -n INT
+Maximum number of alignments to output in the XA tag for reads paired
+properly. If a read has more than INT hits, the XA tag will not be
+written. [3]

+
+Generate alignments in the SAM format given paired-end reads. Repetitive
+read pairs will be placed randomly.
+
+.B OPTIONS:
+.RS
+.TP 8
+.B -a INT
+Maximum insert size for a read pair to be considered being mapped
+properly. Since 0.4.5, this option is only used when there are not
+enough good alignment to infer the distribution of insert sizes. [500]
+.TP
+.B -o INT
+Maximum occurrences of a read for pairing. A read with more occurrneces
+will be treated as a single-end read. Reducing this parameter helps
+faster pairing. [100000]
+.TP
+.B -P
+Load the entire FM-index into memory to reduce disk operations
+(base-space reads only). With this option, at least 1.25N bytes of
+memory are required, where N is the length of the genome.
+.TP
+.B -n INT
+Maximum number of alignments to output in the XA tag for reads paired
+properly. If a read has more than INT hits, the XA tag will not be
+written. [3]
+.TP
+.B -N INT
+Maximum number of alignments to output in the XA tag for disconcordant

+
+.SH NOTES ON SHORT-READ ALIGNMENT
+.SS Alignment Accuracy
+.PP
+When seeding is disabled, BWA guarantees to find an alignment
+containing maximum
+.I maxDiff
+differences including
+.I maxGapO
+gap opens which do not occur within
+.I nIndelEnd
+bp towards either end of the query. Longer gaps may be found if
+.I maxGapE
+is positive, but it is not guaranteed to find all hits. When seeding is
+enabled, BWA further requires that the first
+.I seedLen
+subsequence contains no more than
+.I maxSeedDiff
+differences.
+.PP
+When gapped alignment is disabled, BWA is expected to generate the same
+alignment as Eland, the Illumina alignment program. However, as BWA
+change `N' in the database sequence to random nucleotides, hits to these
+random sequences will also be counted. As a consequence, BWA may mark a
+unique hit as a repeat, if the random sequences happen to be identical
+to the sequences which should be unqiue in the database. This random
+behaviour will be avoided in future releases.
+.PP
+By default, if the best hit is no so repetitive (controlled by -R), BWA
+also finds all hits contains one more mismatch; otherwise, BWA finds all
+equally best hits only. Base quality is NOT considered in evaluating
+hits. In paired-end alignment, BWA pairs all hits it found. It further
+performs Smith-Waterman alignment for unmapped reads with mates mapped
+to rescue mapped mates, and for high-quality anomalous pairs to fix
+potential alignment errors.
+
+.SS Estimating Insert Size Distribution
+.PP
+BWA estimates the insert size distribution per 256*1024 read pairs. It
+first collects pairs of reads with both ends mapped with a single-end
+quality 20 or higher and then calculates median (Q2), lower and higher
+quartile (Q1 and Q3). It estimates the mean and the variance of the
+insert size distribution from pairs whose insert sizes are within
+interval [Q1-2(Q3-Q1), Q3+2(Q3-Q1)]. The maximum distance x for a pair
+considered to be properly paired (SAM flag 0x2) is calculated by solving
+equation Phi((x-mu)/sigma)=x/L*p0, where mu is the mean, sigma is the
+standard error of the insert size distribution, L is the length of the
+genome, p0 is prior of anomalous pair and Phi() is the standard
+cumulative distribution function. For mapping Illumina short-insert
+reads to the human genome, x is about 6-7 sigma away from the
+mean. Quartiles, mean, variance and x will be printed to the standard
+error output.
+
+.SS Memory Requirement
+.PP
+With bwtsw algorithm, 2.5GB memory is required for indexing the complete
+human genome sequences. For short reads, the
+.B `aln'
+command uses ~2.3GB memory and the
+.B `sampe'
+command uses ~3.5GB.
+
+.SS Speed
+.PP
+Indexing the human genome sequences takes 3 hours with bwtsw
+algorithm. Indexing smaller genomes with IS or divsufsort algorithms is
+several times faster, but requires more memory.
+.PP
+Speed of alignment is largely determined by the error rate of the query
+sequences (r). Firstly, BWA runs much faster for near perfect hits than
+for hits with many differences, and it stops searching for a hit with
+l+2 differences if a l-difference hit is found. This means BWA will be
+very slow if r is high because in this case BWA has to visit hits with
+many differences and looking for these hits is expensive. Secondly, the
+alignment algorithm behind makes the speed sensitive to [k log(N)/m],
+where k is the maximum allowed differences, N the size of database and m
+the length of a query. In practice, we choose k w.r.t. r and therefore r
+is the leading factor. I would not recommend to use BWA on data with
+r>0.02.
+.PP
+Pairing is slower for shorter reads. This is mainly because shorter
+reads have more spurious hits and converting SA coordinates to
+chromosomal coordinates are very costly.
+.PP
+In a practical experiment, BWA is able to map 2 million 32bp reads to a
+bacterial genome in several minutes, map the same amount of reads to
+human X chromosome in 8-15 minutes and to the human genome in 15-25
+minutes. This result implies that the speed of BWA is insensitive to the
+size of database and therefore BWA is more efficient when the database
+is sufficiently large. On smaller genomes, hash based algorithms are
+usually much faster.
+
+.SH NOTES ON LONG-READ ALIGNMENT
+.PP
+Command
+.B `bwasw'
+is designed for long-read alignment. The algorithm behind, BWA-SW, is
+similar to BWT-SW, but does not guarantee to find all local hits due to
+the heuristic acceleration. It tends to be faster and more accurate if
+the resultant alignment is supported by more seeds, and therefore
+BWA-SW usually performs better on long queries than on short ones.
+
+On 350-1000bp reads, BWA-SW is several to tens of times faster than the
+existing programs. Its accuracy is comparable to SSAHA2, more accurate
+than BLAT. Like BLAT, BWA-SW also finds chimera which may pose a
+challenge to SSAHA2. On 10-100kbp queries where chimera detection is
+important, BWA-SW is over 10X faster than BLAT while being more
+sensitive.
+
+BWA-SW can also be used to align ~100bp reads, but it is slower than
+the short-read algorithm. Its sensitivity and accuracy is lower than
+SSAHA2 especially when the sequencing error rate is above 2%. This is
+the trade-off of the 30X speed up in comparison to SSAHA2's -454 mode.

+.SH HISTORY
+BWA is largely influenced by BWT-SW. It uses source codes from BWT-SW
+and mimics its binary file formats; BWA-SW resembles BWT-SW in several
+ways. The initial idea about BWT-based alignment also came from the
+group who developed BWT-SW. At the same time, BWA is different enough
+from BWT-SW. The short-read alignment algorithm bears no similarity to
+Smith-Waterman algorithm any more. While BWA-SW learns from BWT-SW, it
+introduces heuristics that can hardly be applied to the original
+algorithm. In all, BWA does not guarantee to find all local hits as what
+BWT-SW is designed to do, but it is much faster than BWT-SW on both
+short and long query sequences.
+
+I started to write the first piece of codes on 24 May 2008 and got the
+initial stable version on 02 June 2008. During this period, I was
+acquainted that Professor Tak-Wah Lam, the first author of BWT-SW paper,
+was collaborating with Beijing Genomics Institute on SOAP2, the successor
+to SOAP (Short Oligonucleotide Analysis Package). SOAP2 has come out in
+November 2008. According to the SourceForge download page, the third
+BWT-based short read aligner, bowtie, was first released in August
+2008. At the time of writing this manual, at least three more BWT-based
+short-read aligners are being implemented.
+
+The BWA-SW algorithm is a new component of BWA. It was conceived in
+November 2008 and implemented ten months later.

+# SYNOPSIS
+#
+#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#          LIBS="$PTHREAD_LIBS $LIBS"
+#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#          CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+Heng Li from the Sanger Institute wrote most of the initial source codes
+of SAMtools and various converters.
+
+Bob Handsaker from the Broad Institute is a major contributor to the
+SAM/BAM specification. He designed and implemented the BGZF format, the
+underlying indexable compression format for the BAM format. BGZF does
+not support arithmetic between file offsets.
+
+Jue Ruan for the Beijing Genome Institute designed and implemented the
+RAZF format, an alternative indexable compression format. RAZF supports
+arithmetic between file offsets, at the cost of increased index file
+size and the full compatibility with gzip. RAZF is optional and only
+used in `faidx' for indexing RAZF compressed fasta files.
+
+Colin Hercus updated novo2sam.pl to support gapped alignment by
+novoalign.
+
+Petr Danecek contributed the header parsing library sam_header.c and 
+sam2vcf.pl script and added knet support to the RAZF library.

+System libraries go *after* user libraries in link commands, because
+the user libraries may themselves have dependencies that are satisfied
+by the system libraries.  It's not rocket science!
+
+This makes a difference with some linkers; or with -static or --as-needed.
+
+The examples/Makefile fix is from Charles Plessy.

+When merging BAM headers, compare the list of target reference sequences
+strictly (and fail/abort if there is a mismatch), but allow one list to be a
+prefix of the other.  (i.e., check that the lists are identical up until the
+shorter runs out, and add the excess targets from the longer to the output.)

+When bam_read1() returns an error (return value <= -2), propagate that error
+to bam_iter_read()'s own return value.  Similarly, also propagate it up to
+bam_fetch()'s return value.  Previously bam_fetch() always returned 0, and
+callers ignored its return value anyway.  With this change, 0 continues to
+indicate success, while <= -2 (which can be written as < 0, as -1 is never
+returned) indicates corrupted input.
+
+bam_iter_read() ought also to propagate errors returned by bam_seek().
+
+main_samview() can now print an error message and fail when bam_fetch()
+detects that a .bai index file is corrupted or otherwise does not correspond
+to the .bam file it is being used with.

+System Requirements
+===================
+
+SAMtools depends on the zlib library <http://www.zlib.net>. Version 1.2.3+ is
+preferred and with 1.2.3+ you can compile razip and use it to compress a FASTA
+file. SAMtools' faidx is able to index a razip-compressed FASTA file to save
+diskspace. Older zlib also works with SAMtools, but razip cannot be compiled.
+
+The text-based viewer (tview) requires the GNU ncurses library
+<http://www.gnu.org/software/ncurses/>, which comes with Mac OS X and most of
+the modern Linux/Unix distributions. If you do not have this library installed,
+you can still compile the rest of SAMtools by manually changing:
+`-D_CURSES_LIB=1' to `-D_CURSES_LIB=0' at the line starting with `DFLAGS=', and
+comment out the line starting with `LIBCURSES='.
+
+
+Compilation
+===========
+
+Type `make' to compile samtools. If you have zlib >= 1.2.2.1, you can compile
+razip with `make razip'.
+
+
+Installation
+============
+
+Copy `samtools', `bcftools/bcftools' and other executables/scripts in `misc' to
+a location you want (e.g. a directory in your $PATH). You may also copy
+`samtools.1' and `bcftools/bcftools.1' to a directory in your $MANPATH such
+that the `man' command may find the manual.

+Beta Release 0.1.16 (21 April, 2011)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes in samtools:
+
+ * Support the new SAM/BAM type `B' in the latest SAM spec v1.4.
+
+ * When the output file of `samtools merge' exists, do not overwrite it unless
+   a new command-line option `-f' is applied.
+
+ * Bugfix: BED support is not working when the input BED is not sorted.
+
+ * Bugfix: some reads without coordinates but given on the reverse strand are
+   lost in merging.
+
+Notable changes in bcftools:
+
+ * Code cleanup: separated max-likelihood inference and Bayesian inference.
+
+ * Test Hardy-Weinberg equilibrium with a likelihood-ratio test.
+
+ * Provided another association test P-value by likelihood-ratio test.
+
+ * Use Brent's method to estimate the site allele frequency when EM converges
+   slowly. The resulting ML estimate of allele frequnecy is more accurate.
+
+ * Added the `ldpair' command, which computes r^2 between SNP pairs given in
+   an input file.
+
+Also, the `pileup' command, which has been deprecated by `mpileup' since
+version 0.1.10, will be dropped in the next release. The old `pileup' command
+is substandard and causing a lot of confusion.
+
+(0.1.16: 21 April 2011, r963:234)
+
+
+
+Beta Release 0.1.15 (10 April, 2011)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Noteable changes:
+
+ * Allow to perform variant calling or to extract information in multiple
+   regions specified by a BED file (`samtools mpileup -l', `samtools view -L'
+   and `bcftools view -l').
+
+ * Added the `depth' command to samtools to compute the per-base depth with a
+   simpler interface. File `bam2depth.c', which implements this command, is the
+   recommended example on how to use the mpileup APIs.
+
+ * Estimate genotype frequencies with ML; perform chi^2 based Hardy-Weinberg
+   test using this estimate.
+
+ * For `samtools view', when `-R' is specified, drop read groups in the header
+   that are not contained in the specified file.
+
+ * For `samtools flagstat', separate QC-pass and QC-fail reads.
+
+ * Improved the command line help of `samtools mpileup' and `bcftools view'.
+
+ * Use a global variable to control the verbose level of samtools stderr
+   output. Nonetheless, it has not been full utilized.
+
+ * Fixed an issue in association test which may report false associations,
+   possibly due to floating point underflow.
+
+(0.1.15: 10 April 2011, r949:203)
+
+
+
+Beta release 0.1.14 (21 March, 2011)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This release implements a method for testing associations for case-control
+data. The method does not call genotypes but instead sums over all genotype
+configurations to compute a chi^2 based test statistics. It can be potentially
+applied to comparing a pair of samples (e.g. a tumor-normal pair), but this
+has not been evaluated on real data.
+
+Another new feature is to make X chromosome variant calls when female and male
+samples are both present. The user needs to provide a file indicating the
+ploidy of each sample (see also manual bcftools/bcftools.1).
+
+Other notable changes:
+
+ * Added `bcftools view -F' to parse BCF files generated by samtools r921 or
+   older which encodes PL in a different way.
+
+ * Changed the behavior of `bcftools view -s'. Now when a list of samples is
+   provided, the samples in the output will be reordered to match the ordering
+   in the sample list. This change is mainly designed for association test.
+
+ * Sped up `bcftools view -v' for target sequencing given thousands of samples.
+   Also added a new option `view -d' to skip loci where only a few samples are
+   covered by reads.
+
+ * Dropped HWE test. This feature has never been implemented properly. An EM
+   should be much better. To be implemented in future.
+
+ * Added the `cat' command to samtools. This command concatenate BAMs with
+   identical sequence dictionaries in an efficient way. Modified from bam_cat.c
+   written by Chris Saunders.
+
+ * Added `samtools view -1' to write BAMs at a low compression level but twice
+   faster to create. The `sort' command generates temporary files at a low
+   compression level as well.
+
+ * Added `samtools mpileup -6' to accept "BAM" with Illumina 1.3+ quality
+   strings (strictly speaking, such a file is not BAM).
+
+ * Added `samtools mpileup -L' to skip INDEL calling in regions with
+   excessively high coverage. Such regions dramatically slow down mpileup.
+
+ * Updated `misc/export2sam.pl', provided by Chris Saunders from Illumina Inc.
+
+(0.1.14: 21 March 2011, r933:170)
+
+
+
+Beta release 0.1.13 (1 March, 2011)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The most important though largely invisible modification is the change of the
+order of genotypes in the PL VCF/BCF tag. This is to conform the upcoming VCF
+spec v4.1. The change means that 0.1.13 is not backward compatible with VCF/BCF
+generated by samtools older than r921 inclusive.  VCF/BCF generated by the new
+samtools will contain a line `##fileformat=VCFv4.1' as well as the samtools
+version number.
+
+Single Individual Haplotyping (SIH) is added as an experimental feature. It
+originally aims to produce haploid consensus from fosmid pool sequencing, but
+also works with short-read data. For short reads, phased blocks are usually too
+short to be useful in many applications, but they can help to rule out part of
+SNPs close to INDELs or between copies of CNVs.
+
+
+Other notable changes in samtools:
+
+ * Construct per-sample consensus to reduce the effect of nearby SNPs in INDEL
+   calling. This reduces the power but improves specificity.
+
+ * Improved sorting order checking in indexing. Now indexing is the preferred way
+   to check if a BAM is sorted.
+
+ * Added a switch `-E' to mpileup and calmd. This option uses an alternative way
+   to apply BAQ, which increases sensistivity, especially to MNPs, at the cost of
+   a little loss in specificity.
+
+ * Added `mpileup -A' to allow to use reads in anomalous pairs in SNP calling.
+
+ * Added `mpileup -m' to allow fine control of the collection of INDEL candidates.
+
+ * Added `mpileup -S' to compute per-sample strand bias P-value.
+
+ * Added `mpileup -G' to exclude read groups in variant calling.
+
+ * Fixed segfault in indel calling related to unmapped and refskip reads.
+
+ * Fixed an integer overflow in INDEL calling. This bug produces wrong INDEL
+   genotypes for longer short INDELs, typically over 10bp.
+
+ * Fixed a bug in tview on big-endian machines.
+
+ * Fixed a very rare memory issue in bam_md.c
+
+ * Fixed an out-of-boundary bug in mpileup when the read base is `N'.
+
+ * Fixed a compiling error when the knetfile library is not used. Fixed a
+   library compiling error due to the lack of bam_nt16_nt4_table[] table.
+   Suppress a compiling warning related to the latest zlib.
+
+
+Other notable changes in bcftools:
+
+ * Updated the BCF spec.
+
+ * Added the `FQ' VCF INFO field, which gives the phred-scaled probability
+   of all samples being the same (identical to the reference or all homozygous
+   variants). Option `view -f' has been dropped.
+
+ * Implementated of "vcfutils.pl vcf2fq" to generate a consensus sequence
+   similar to "samtools.pl pileup2fq".
+
+ * Make sure the GT FORMAT field is always the first FORMAT to conform the VCF
+   spec. Drop bcf-fix.pl.
+
+ * Output bcftools specific INFO and FORMAT in the VCF header.
+
+ * Added `view -s' to call variants from a subset of samples.
+
+ * Properly convert VCF to BCF with a user provided sequence dictionary. Nonetheless,
+   custom fields are still unparsed and will be stored as a missing value.
+
+ * Fixed a minor bug in Fisher's exact test; the results are rarely changed.
+
+
+(0.1.13: 1 March 2011, r926:134)
+
+
+
+Beta release 0.1.12a (2 December, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is another bug fix release:
+
+ * Fixed a memory violation in mpileup, which causes segfault. Release
+   0.1.9 and above are affected.
+
+ * Fixed a memory violation in the indel caller, which does not causes
+   segfault, but may potentially affect deletion calls in an unexpected
+   way. Release 0.1.10 and above are affected.
+
+ * Fixed a bug in computing r-square in bcftools. Few are using this
+   functionality and it only has minor effect.
+
+ * Fixed a memory leak in bam_fetch().
+
+ * Fixed a bug in writing meta information to the BAM index for the last
+   sequence. This bug is invisible to most users, but it is a bug anyway.
+
+ * Fixed a bug in bcftools which causes false "DP4=0,0,0,0" annotations.
+
+(0.1.12: 2 December 2010, r862)
+
+
+
+Beta release 0.1.11 (21 November, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is mainly a bug fix release:
+
+ * Fixed a bug in random retrieval (since 0.1.8). It occurs when reads
+   are retrieved from a small region containing no reads.
+
+ * Fixed a bug in pileup (since 0.1.9). The bug causes an assertion
+   failure when the first CIGAR operation is a deletion.
+
+ * Improved fault tolerence in remote access.
+
+One minor feature has been implemented in bcftools:
+
+ * Added a reference-free variant calling mode. In this mode, a site is
+   regarded as a variat iff the sample(s) contains two or more alleles;
+   the meaning of the QUAL field in the VCF output is changed
+   accordingly. Effectively, the reference allele is irrelevant to the
+   result in the new mode, although the reference sequence has to be
+   used in realignment when SAMtools computes genotype likelihoods.
+
+In addition, since 0.1.10, the `pileup' command has been deprecated by
+`mpileup' which is more powerful and more accurate. The `pileup' command
+will not be removed in the next few releases, but new features will not
+be added.
+
+(0.1.11: 21 November 2010, r851)
+
+
+
+Beta Release 0.1.10 (16 November, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This release is featured as the first major improvement to the indel
+caller. The method is similar to the old one implemented in the pileup
+command, but the details are handled more carefully both in theory and
+in practice. As a result, the new indel caller usually gives more
+accurate indel calls, though at the cost of sensitivity. The caller is
+implemented in the mpileup command and is invoked by default. It works
+with multiple samples.
+
+Other notable changes:
+
+ * With the -r option, the calmd command writes the difference between
+   the original base quality and the BAQ capped base quality at the BQ
+   tag but does not modify the base quality. Please use -Ar to overwrite
+   the original base quality (the 0.1.9 behavior).
+
+ * Allow to set a maximum per-sample read depth to reduce memory. In
+   0.1.9, most of memory is wasted for the ultra high read depth in some
+   regions (e.g. the chr1 centromere).
+
+ * Optionally write per-sample read depth and per-sample strand bias
+   P-value.
+
+ * Compute equal-tail (Bayesian) credible interval of site allele
+   frequency at the CI95 VCF annotation.
+
+ * Merged the vcfutils.pl varFilter and filter4vcf for better SNP/indel
+   filtering.
+
+(0.1.10: 16 November 2010, r829)
+
+
+
+Beta Release 0.1.9 (27 October, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This release is featured as the first major improvement to the samtools'
+SNP caller.  It comes with a revised MAQ error model, the support of
+multi-sample SNP calling and the computation of base alignment quality
+(BAQ).
+
+The revised MAQ error model is based on the original model. It solves an
+issue of miscalling SNPs in repetitive regions. Althought such SNPs can
+usually be filtered at a later step, they mess up unfiltered calls. This
+is a theoretical flaw in the original model. The revised MAQ model
+deprecates the orginal MAQ model and the simplified SOAPsnp model.
+
+Multi-sample SNP calling is separated in two steps. The first is done by
+samtools mpileup and the second by a new program, bcftools, which is
+included in the samtools source code tree. Multi-sample SNP calling also
+works for single sample and has the advantage of enabling more powerful
+filtration. It is likely to deprecate pileup in future once a proper
+indel calling method is implemented.
+
+BAQ is the Phred-scaled probability of a read base being wrongly
+aligned. Capping base quality by BAQ has been shown to be very effective
+in suppressing false SNPs caused by misalignments around indels or in
+low-complexity regions with acceptable compromise on computation
+time. This strategy is highly recommended and can be used with other SNP
+callers as well.
+
+In addition to the three major improvements, other notable changes are:
+
+ * Changes to the pileup format. A reference skip (the N CIGAR operator)
+   is shown as '<' or '>' depending on the strand. Tview is also changed
+   accordingly.
+
+ * Accelerated pileup. The plain pileup is about 50% faster.
+
+ * Regional merge. The merge command now accepts a new option to merge
+   files in a specified region.
+
+ * Fixed a bug in bgzip and razip which causes source files to be
+   deleted even if option -c is applied.
+
+ * In APIs, propogate errors to downstream callers and make samtools
+   return non-zero values once errors occur.
+
+(0.1.9: 27 October 2010, r783)
+
+
+
+Beta Release 0.1.8 (11 July, 2010)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable functional changes:
+
+ * Added the `reheader' command which replaces a BAM header with a new
+   header. This command is much faster than replacing header by
+   BAM->SAM->BAM conversions.
+
+ * Added the `mpileup' command which computes the pileup of multiple
+   alignments.
+
+ * The `index' command now stores the number of mapped and unmapped
+   reads in the index file. This information can be retrieved quickly by
+   the new `idxstats' command.
+
+ * By default, pileup used the SOAPsnp model for SNP calling. This
+   avoids the floating overflow in the MAQ model which leads to spurious
+   calls in repetitive regions, although these calls will be immediately
+   filtered by varFilter.
+
+ * The `tview' command now correctly handles CIGARs like 7I10M and
+   10M1P1I10M which cause assertion failure in earlier versions.
+
+ * Tview accepts a region like `=10,000' where `=' stands for the
+   current sequence name. This saves typing for long sequence names.
+
+ * Added the `-d' option to `pileup' which avoids slow indel calling
+   in ultradeep regions by subsampling reads locally.
+
+ * Added the `-R' option to `view' which retrieves alignments in read
+   groups listed in the specified file.
+
+Performance improvements:
+
+ * The BAM->SAM conversion is up to twice faster, depending on the
+   characteristic of the input.
+
+ * Parsing SAM headers with a lot of reference sequences is now much
+   faster.
+
+ * The number of lseek() calls per query is reduced when the query
+   region contains no read alignments.
+
+Bug fixes:
+
+ * Fixed an issue in the indel caller that leads to miscall of indels.
+   Note that this solution may not work well when the sequencing indel
+   error rate is higher than the rate of SNPs.
+
+ * Fixed another issue in the indel caller which may lead to incorrect
+   genotype.
+
+ * Fixed a bug in `sort' when option `-o' is applied.
+
+ * Fixed a bug in `view -r'.
+
+APIs and other changes:
+
+ * Added iterator interfaces to random access and pileup. The callback
+   interfaces directly call the iterator interfaces.
+
+ * The BGZF blocks holding the BAM header are indepedent of alignment
+   BGZF blocks. Alignment records shorter than 64kB is guaranteed to be
+   fully contained in one BGZF block. This change is fully compatible
+   with the old version of samtools/picard.
+
+Changes in other utilities:
+
+ * Updated export2sam.pl by Chris Saunders.
+
+ * Improved the sam2vcf.pl script.
+
+ * Added a Python version of varfilter.py by Aylwyn Scally.
+
+(0.1.8: 11 July 2010, r613)
+
+
+
+Beta Release 0.1.7 (10 November, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes:
+
+ * Improved the indel caller in complex scenariors, in particular for
+   long reads. The indel caller is now able to make reasonable indel
+   calls from Craig Venter capillary reads.
+
+ * Rewrote single-end duplicate removal with improved
+   performance. Paired-end reads are not touched.
+
+ * Duplicate removal is now library aware. Samtools remove potential
+   PCR/optical dupliates inside a library rather than across libraries.
+
+ * SAM header is now fully parsed, although this functionality is not
+   used in merging and so on.
+
+ * In samtools merge, optionally take the input file name as RG-ID and
+   attach the RG tag to each alignment.
+
+ * Added FTP support in the RAZF library. RAZF-compressed reference
+   sequence can be retrieved remotely.
+
+ * Improved network support for Win32.
+
+ * Samtools sort and merge are now stable.
+
+Changes in other utilities:
+
+ * Implemented sam2vcf.pl that converts the pileup format to the VCF
+   format.
+
+ * This release of samtools is known to work with the latest
+   Bio-Samtools Perl module.
+
+(0.1.7: 10 November 2009, r510)
+
+
+
+Beta Release 0.1.6 (2 September, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes:
+
+ * In tview, do not show a blank screen when no reads mapped to the
+   corresponding region.
+
+ * Implemented native HTTP support in the BGZF library. Samtools is now
+   able to directly open a BAM file on HTTP. HTTP proxy is also
+   supported via the "http_proxy" environmental variable.
+
+ * Samtools is now compitable with the MinGW (win32) compiler and the
+   PDCurses library.
+
+ * The calmd (or fillmd) command now calculates the NM tag and replaces
+   MD tags if they are wrong.
+
+ * The view command now recognizes and optionally prints FLAG in HEXs or
+   strings to make a SAM file more friendly to human eyes. This is a
+   samtools-C extension, not implemented in Picard for the time
+   being. Please type `samtools view -?' for more information.
+
+ * BAM files now have an end-of-file (EOF) marker to facilitate
+   truncation detection. A warning will be given if an on-disk BAM file
+   does not have this marker. The warning will be seen on BAM files
+   generated by an older version of samtools. It does NO harm.
+
+ * New key bindings in tview: `r' to show read names and `s' to show
+   reference skip (N operation) as deletions.
+
+ * Fixed a bug in `samtools merge -n'.
+
+ * Samtools merge now optionally copies the header of a user specified
+   SAM file to the resultant BAM output.
+
+ * Samtools pileup/tview works with a CIGAR with the first or the last
+   operation is an indel.
+
+ * Fixed a bug in bam_aux_get().
+
+
+Changes in other utilies:
+
+ * Fixed wrong FLAG in maq2sam.
+
+
+(0.1.6: 2 September 2009, r453)
+
+
+
+Beta Release 0.1.5 (7 July, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes:
+
+ * Support opening a BAM alignment on FTP. Users can now use "tview" to
+   view alignments at the NCBI ftp site. Please read manual for more
+   information.
+
+ * In library, propagate errors rather than exit or complain assertion
+   failure.
+
+ * Simplified the building system and fixed compiling errors caused by
+   zlib<1.2.2.1.
+
+ * Fixed an issue about lost header information when a SAM is imported
+   with "view -t".
+
+ * Implemented "samtool.pl varFilter" which filters both SNPs and short
+   indels. This command replaces "indelFilter".
+
+ * Implemented "samtools.pl pileup2fq" to generate FASTQ consensus from
+   pileup output.
+
+ * In pileup, cap mapping quality at 60. This helps filtering when
+   different aligners are in use.
+
+ * In pileup, allow to output variant sites only.
+
+ * Made pileup generate correct calls in repetitive region. At the same
+   time, I am considering to implement a simplified model in SOAPsnp,
+   although this has not happened yet.
+
+ * In view, added '-u' option to output BAM without compression. This
+   option is preferred when the output is piped to other commands.
+
+ * In view, added '-l' and '-r' to get the alignments for one library or
+   read group. The "@RG" header lines are now partially parsed.
+
+ * Do not include command line utilities to libbam.a.
+
+ * Fixed memory leaks in pileup and bam_view1().
+
+ * Made faidx more tolerant to empty lines right before or after FASTA >
+   lines.
+
+
+Changes in other utilities:
+
+ * Updated novo2sam.pl by Colin Hercus, the key developer of novoalign.
+
+
+This release involves several modifications to the key code base which
+may potentially introduce new bugs even though we have tried to minimize
+this by testing on several examples. Please let us know if you catch
+bugs.
+
+(0.1.5: 7 July 2009, r373)
+
+
+
+Beta Release 0.1.4 (21 May, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes:
+
+ * Added the 'rmdupse' command: removing duplicates for SE reads.
+
+ * Fixed a critical bug in the indel caller: clipped alignments are not
+   processed correctly.
+
+ * Fixed a bug in the tview: gapped alignment may be incorrectly
+   displayed.
+
+ * Unified the interface to BAM and SAM I/O. This is done by
+   implementing a wrapper on top of the old APIs and therefore old APIs
+   are still valid. The new I/O APIs also recognize the @SQ header
+   lines.
+
+ * Generate the MD tag.
+
+ * Generate "=" bases. However, the indel caller will not work when "="
+   bases are present.
+
+ * Enhanced support of color-read display (by Nils Homer).
+
+ * Implemented the GNU building system. However, currently the building
+   system does not generate libbam.a. We will improve this later. For
+   the time being, `make -f Makefile.generic' is preferred.
+
+ * Fixed a minor bug in pileup: the first read in a chromosome may be
+   skipped.
+
+ * Fixed bugs in bam_aux.c. These bugs do not affect other components as
+   they were not used previously.
+
+ * Output the 'SM' tag from maq2sam.
+
+(0.1.4: 21 May 2009, r297)
+
+
+
+Beta Release 0.1.3 (15 April, 2009)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes in SAMtools:
+
+ * SAMtools is more consistent with the specification: a) '*' in the
+   QUAL field is allowed; b) the field separator is TAB only and SPACE
+   is treated as a character in a field; c) empty header is allowed.
+
+ * Implemented GLFv3 support in pileup.
+
+ * Fixed a severe bug in fixmate: strand information is wrongly
+   overwritten.
+
+ * Fixed a bug in alignment retrieval: alignments bridging n*16384bp are
+   not correctly retrieved sometimes.
+
+ * Fixed a bug in rmdup: segfault if unmapped reads are present.
+
+ * Move indel_filter.pl to samtools.pl and improved the filtering by
+   checking the actual number of alignments containing indels. The indel
+   pileup line is also changed a little to make this filtration easier.
+
+ * Fixed a minor bug in indexing: the bin number of an unmapped read is
+   wrongly calculated.
+
+ * Added `flagstat' command to show statistics on the FLAG field.
+
+ * Improved indel caller by setting the maximum window size in local
+   realignment.
+
+Changes in other utilities:
+
+ * Fixed a bug in maq2sam: a tag name is obsolete.
+
+ * Improvement to wgsim: a) added support for SOLiD read simulation; b)
+   show the number of substitutions/indels/errors in read name; c)
+   considerable code clean up.
+
+ * Various converters: improved functionality in general.
+
+ * Updated the example SAM due to the previous bug in fixmate.
+
+(0.1.3: 15 April 2009, r227)
+
+
+
+Beta Release 0.1.2 (28 January, 2008)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Notable changes in SAMtools:
+
+ * Implemented a Bayesian indel caller. The new caller generate scores
+   and genotype and is potentially more accurate than Maq's indel
+   caller. The pileup format is also changed accordingly.
+
+ * Implemented rmdup command: remove potential PCR duplicates. Note that
+   this command ONLY works for FR orientation and requires ISIZE is
+   correctly set.
+
+ * Added fixmate command: fill in mate coordinates, ISIZE and mate
+   related flags from a name-sorted alignment.
+
+ * Fixed a bug in indexing: reads bridging 16x kbp were not retrieved.
+
+ * Allow to select reads shown in the pileup output with a mask.
+
+ * Generate GLFv2 from pileup.
+
+ * Added two more flags for flagging PCR/optical duplicates and for QC
+   failure.
+
+ * Fixed a bug in sort command: name sorting for large alignment did not
+   work.
+
+ * Allow to completely disable RAZF (using Makefile.lite) as some people
+   have problem to compile it.
+
+ * Fixed a bug in import command when there are reads without
+   coordinates.
+
+ * Fixed a bug in tview: clipping broke the alignment viewer.
+
+ * Fixed a compiling error when _NO_CURSES is applied.
+
+ * Fixed a bug in merge command.
+
+Changes in other utilities:
+
+ * Added wgsim, a paired-end reads simulator. Wgsim was adapted from
+   maq's reads simulator. Colin Hercus further improved it to allow
+   longer indels.
+
+ * Added wgsim_eval.pl, a script that evaluates the accuracy of
+   alignment on reads generated by wgsim.
+
+ * Added soap2sam.pl, a SOAP2->SAM converter. This converter does not
+   work properly when multiple hits are output.
+
+ * Added bowtie2sam.pl, a Bowtie->SAM converter. Only the top hit will
+   be retained when multiple hits are present.
+
+ * Fixed a bug in export2sam.pl for QC reads.
+
+ * Support RG tag at MAQ->SAM converter.
+
+ * Added novo2sam.pl, a NovoAlign->SAM converter. Multiple hits and
+   indel are not properly handled, though.
+
+ * Added zoom2sam.pl, a ZOOM->SAM converter. It only works with the
+   default Illumina output.

+
+bam_cat -- efficiently concatenates bam files
+
+bam_cat can be used to concatenate BAM files. Under special
+circumstances, it can be used as an alternative to 'samtools merge' to
+concatenate multiple sorted files into a single sorted file. For this
+to work each file must be sorted, and the sorted files must be given
+as command line arguments in order such that the final read in file i
+is less than or equal to the first read in file i+1.
+
+This code is derived from the bam_reheader function in samtools 0.1.8
+and modified to perform concatenation by Chris Saunders on behalf of
+Illumina.

+
+  Alignment indexing. Before indexing, BAM must be sorted based on the
+  leftmost coordinate of alignments. In indexing, BAM uses two indices:
+  a UCSC binning index and a simple linear index. The binning index is
+  efficient for alignments spanning long distance, while the auxiliary
+  linear index helps to reduce unnecessary seek calls especially for
+  short alignments.
+
+  The UCSC binning scheme was suggested by Richard Durbin and Lincoln
+  Stein and is explained by Kent et al. (2002). In this scheme, each bin
+  represents a contiguous genomic region which can be fully contained in
+  another bin; each alignment is associated with a bin which represents
+  the smallest region containing the entire alignment. The binning
+  scheme is essentially another representation of R-tree. A distinct bin
+  uniquely corresponds to a distinct internal node in a R-tree. Bin A is
+  a child of Bin B if region A is contained in B.
+
+  In BAM, each bin may span 2^29, 2^26, 2^23, 2^20, 2^17 or 2^14 bp. Bin
+  0 spans a 512Mbp region, bins 1-8 span 64Mbp, 9-72 8Mbp, 73-584 1Mbp,
+  585-4680 128Kbp and bins 4681-37449 span 16Kbp regions. If we want to
+  find the alignments overlapped with a region [rbeg,rend), we need to
+  calculate the list of bins that may be overlapped the region and test
+  the alignments in the bins to confirm the overlaps. If the specified
+  region is short, typically only a few alignments in six bins need to
+  be retrieved. The overlapping alignments can be quickly fetched.

+The view command of bcftools calls variants, tests Hardy-Weinberg
+equilibrium (HWE), tests allele balances and estimates allele frequency.
+
+This command calls a site as a potential variant if P(ref|D,F) is below
+0.9 (controlled by the -p option), where D is data and F is the prior
+allele frequency spectrum (AFS).
+
+The view command performs two types of allele balance tests, both based
+on Fisher's exact test for 2x2 contingency tables with the row variable
+being reference allele or not. In the first table, the column variable
+is strand. Two-tail P-value is taken. We test if variant bases tend to
+come from one strand. In the second table, the column variable is
+whether a base appears in the first or the last 11bp of the read.
+One-tail P-value is taken. We test if variant bases tend to occur
+towards the end of reads, which is usually an indication of
+misalignment.
+
+Site allele frequency is estimated in two ways. In the first way, the
+frequency is esimated as \argmax_f P(D|f) under the assumption of
+HWE. Prior AFS is not used. In the second way, the frequency is
+estimated as the posterior expectation of allele counts \sum_k
+kP(k|D,F), dividied by the total number of haplotypes. HWE is not
+assumed, but the estimate depends on the prior AFS. The two estimates
+largely agree when the signal is strong, but may differ greatly on weak
+sites as in this case, the prior plays an important role.
+
+To test HWE, we calculate the posterior distribution of genotypes
+(ref-hom, het and alt-hom). Chi-square test is performed. It is worth
+noting that the model used here is prior dependent and assumes HWE,
+which is different from both models for allele frequency estimate. The
+new model actually yields a third estimate of site allele frequency.
+
+The estimate allele frequency spectrum is printed to stderr per 64k
+sites. The estimate is in fact only the first round of a EM
+procedure. The second model (not the model for HWE testing) is used to
+estimate the AFS.

+\item A BCF file is in the {\tt BGZF} format.
+\item All multi-byte numbers are little-endian.
+\item In a string, a missing value `.' is an empty C string ``{\tt
+    \char92 0}'' (not ``{\tt .\char92 0}'')
+\item For {\tt GL} and {\tt PL}, likelihoods of genotypes appear in the
+  order of alleles in {\tt REF} and then {\tt ALT}. For example, if {\tt
+    REF=C}, {\tt ALT=T,A}, likelihoods appear in the order of {\tt
+    CC,CT,TT,CA,TA,AA} (NB: the ordering is different from the one in the original
+	BCF proposal).
+\item Predefined {\tt FORMAT} fields can be missing from VCF headers, but custom {\tt FORMAT} fields
+	are required to be explicitly defined in the headers.
+\item A {\tt FORMAT} field with its name starting with `{\tt \_}' is specific to BCF only.
+	It gives an alternative binary representation of the corresponding VCF field, in case
+	the default representation is unable to keep the genotype information,
+	for example, when the ploidy is not 2 or there are more than 8 alleles.

+frequencies.
+
+.RS
+.TP
+.B Input/Output Options:
+.TP 10
+.B -A
+Retain all possible alternate alleles at variant sites. By default, the view
+command discards unlikely alleles.
+.TP 10
+.B -b
+Output in the BCF format. The default is VCF.
+.TP
+.BI -D \ FILE
+Sequence dictionary (list of chromosome names) for VCF->BCF conversion [null]
+.TP
+.B -F
+Indicate PL is generated by r921 or before (ordering is different).
+.TP
+.B -G
+Suppress all individual genotype information.
+.TP
+.BI -l \ FILE
+List of sites at which information are outputted [all sites]
+.TP
+.B -N
+Skip sites where the REF field is not A/C/G/T
+.TP
+.B -Q
+Output the QCALL likelihood format
+.TP
+.BI -s \ FILE
+List of samples to use. The first column in the input gives the sample names
+and the second gives the ploidy, which can only be 1 or 2. When the 2nd column
+is absent, the sample ploidy is assumed to be 2. In the output, the ordering of
+samples will be identical to the one in
+.IR FILE .
+[null]
+.TP
+.B -S
+The input is VCF instead of BCF.
+.TP
+.B -u
+Uncompressed BCF output (force -b).
+.TP
+.B Consensus/Variant Calling Options:
+.TP 10
+.B -c
+Call variants using Bayesian inference. This option automatically invokes option
+.BR -e .
+.TP
+.BI -d \ FLOAT
+When
+.B -v
+is in use, skip loci where the fraction of samples covered by reads is below FLOAT. [0]
+.TP
+.B -e
+Perform max-likelihood inference only, including estimating the site allele frequency,
+testing Hardy-Weinberg equlibrium and testing associations with LRT.
+.TP
+.B -g
+Call per-sample genotypes at variant sites (force -c)
+.TP
+.BI -i \ FLOAT
+Ratio of INDEL-to-SNP mutation rate [0.15]
+.TP
+.BI -p \ FLOAT
+A site is considered to be a variant if P(ref|D)<FLOAT [0.5]
+.TP
+.BI -P \ STR
+Prior or initial allele frequency spectrum. If STR can be
+.IR full ,
+.IR cond2 ,
+.I flat
+or the file consisting of error output from a previous variant calling
+run.
+.TP
+.BI -t \ FLOAT
+Scaled muttion rate for variant calling [0.001]
+.TP
+.B -v
+Output variant sites only (force -c)
+.TP
+.B Contrast Calling and Association Test Options:
+.TP
+.BI -1 \ INT
+Number of group-1 samples. This option is used for dividing the samples into
+two groups for contrast SNP calling or association test.
+When this option is in use, the following VCF INFO will be outputted:
+PC2, PCHI2 and QCHI2. [0]
+.TP
+.BI -U \ INT
+Number of permutations for association test (effective only with
+.BR -1 )
+[0]

+ 
+   Based on the pseudocodes by Bell and Pike (CACM 9(9):684-685), and
+   the revision by Tomlin and Smith (CACM 12(11):637-638). Both of the
+   papers are comments on Kaupe's Algorithm 178 "Direct Search" (ACM

+   Johnson's implementation at Netlib (opt/hooke.c).
+ 
+   Hooke-Jeeves algorithm is very simple and it works quite well on a
+   few examples. However, it might fail to converge due to its heuristic
+   nature. A possible improvement, as is suggested by Johnson, may be to
+   choose a small r at the beginning to quickly approach to the minimum
+   and a large r at later step to hit the minimum.

+File ex1.fa contains two sequences cut from the human genome
+build36. They were exatracted with command:
+
+  samtools faidx human_b36.fa 2:2043966-2045540 20:67967-69550
+
+Sequence names were changed manually for simplicity. File ex1.sam.gz
+contains MAQ alignments exatracted with:
+
+  (samtools view NA18507_maq.bam 2:2044001-2045500;
+   samtools view NA18507_maq.bam 20:68001-69500)
+
+and processed with `samtools fixmate' to make it self-consistent as a
+standalone alignment.
+
+To try samtools, you may run the following commands:
+
+  samtools faidx ex1.fa                 # index the reference FASTA
+  samtools import ex1.fa.fai ex1.sam.gz ex1.bam   # SAM->BAM
+  samtools index ex1.bam                # index BAM
+  samtools tview ex1.bam ex1.fa         # view alignment
+  samtools pileup -cf ex1.fa ex1.bam    # pileup and consensus
+  samtools pileup -cf ex1.fa -t ex1.fa.fai ex1.sam.gz

+    * Fixed a bug in introsort() that happens in rare cases.
+
+  2008-11-05 (0.1.3):
+
+    * Fixed a bug in introsort() for complex comparisons.
+
+	* Fixed a bug in mergesort(). The previous version is not stable.
+
+  2008-09-15 (0.1.2):
+
+	* Accelerated introsort. On my Mac (not on another Linux machine),
+	  my implementation is as fast as std::sort on random input.
+
+	* Added combsort and in introsort, switch to combsort if the
+	  recursion is too deep.
+
+  2008-09-13 (0.1.1):
+
+	* Added k-small algorithm

+#
+########## ChangeLog:
+#
+# Version: 2.3.1 (18MAR2011)
+#
+#   - Restore file '-' as stdin input.
+#
+# Version: 2.3.0 (24JAN2011)
+#
+#   - Add support for export reserved chromosome name "CONTROL",
+#       which is translated to optional field "XC:Z:CONTROL".
+#   - Check for ".gz" file extension on export files and open
+#       these as gzip pipes when the extension is found.
+#
+# Version: 2.2.0 (16NOV2010)
+#
+#   - Remove any leading zeros in export fields: RUNNO,LANE,TILE,X,Y
+#   - For export records with reserved chromosome name identifiers
+#       "QC" and "RM", add the optional field "XC:Z:QC" or "XC:Z:RM"
+#       to the SAM record, so that these cases can be distinguished
+#       from other unmatched reads.
+#
+# Version: 2.1.0 (21SEP2010)
+#
+#   - Additional export record error checking.
+#   - Convert export records with chromomsome value of "RM" to unmapped 
+#       SAM records.
+#
+# Version: 2.0.0 (15FEB2010)
+#
+#   Script updated by Illumina in conjunction with CASAVA 1.7.0
+#   release.
+#
+#   Major changes are as follows:
+#   - The CIGAR string has been updated to include all gaps from
+#       ELANDv2 alignments.
+#   - The ELAND single read alignment score is always stored in the
+#       optional "SM" field and the ELAND paired read alignment score
+#       is stored in the optional "AS" field when it exists.
+#   - The MAPQ value is set to the higher of the two alignment scores,
+#       but no greater than 254, i.e. min(254,max(SM,AS))
+#   - The SAM "proper pair" bit (0x0002) is now set for read pairs
+#       meeting ELAND's expected orientation and insert size criteria.
+#   - The default quality score translation is set for export files
+#       which contain Phread+64 quality values. An option,
+#       "--qlogodds", has been added to translate quality values from
+#       the Solexa+64 format used in export files prior to Pipeline
+#       1.3
+#   - The export match descriptor is now reverse-complemented when
+#       necessary such that it always corresponds to the forward
+#       strand of the reference, to be consistent with other
+#       information in the SAM record. It is now written to the
+#       optional 'XD' field (rather than 'MD') to acknowledge its
+#       minor differences from the samtools match descriptor (see
+#       additional detail below).
+#   - An option, "--nofilter", has been added to include reads which
+#       have failed primary analysis quality filtration. Such reads
+#       will have the corresponding SAM flag bit (0x0200) set.
+#   - Labels in the export 'contig' field are preserved by setting
+#       RNAME to "$export_chromosome/$export_contig" when the contig
+#       label exists.
+#
+#
+# Contact: lh3
+# Version: 0.1.2 (03JAN2009)
+#
+#
+#
+########## Known Conversion Limitations:
+#
+# - Export records for reads that map to a position < 1 (allowed
+#     in export format), are converted to unmapped reads in the SAM
+#     record.
+# - Export records contain the reserved chromosome names: "NM",
+#     "QC","RM" and "CONTROL". "NM" indicates that the aligner could
+#     not map the read to the reference sequence set. "QC" means that
+#     the aligner did not attempt to map the read due to some
+#     technical limitation. "RM" means that the read mapped to a set
+#     of 'contaminant' sequences specified in GERALD's RNA-seq
+#     workflow. "CONTROL" means that the read is a control. All of
+#     these alignment types are collapsed to the single unmapped
+#     alignment state in the SAM record, but the optional SAM "XC"
+#     field is used to record the original reserved chromosome name of
+#     the read for all but the "NM" case.
+# - The export match descriptor is slightly different than the
+#     samtools match descriptor. For this reason it is stored in the
+#     optional SAM field 'XD' (and not 'MD'). Note that the export
+#     match descriptor differs from the samtools version in two
+#     respects: (1) indels are explicitly closed with the '$'
+#     character and (2) insertions must be enumerated in the match
+#     descriptor. For example a 35-base read with a two-base insertion
+#     is described as: 20^2$14
+#

+# About:
+#   varfilter.py is a port of Heng's samtools.pl varFilter script into 
+#   python, with an additional -C INT option. This option sets a minimum 
+#   consensus score, above which the script will output a pileup line 
+#   wherever it _could have_ called a variant, even if none is actually 
+#   called (i.e. hom-ref positions). This is important if you want to
+#   subsequently merge the calls with those for another individual to get a
+#   synoptic view of calls at each site. Without this option, and in all 
+#   other respects, it behaves like samtools.pl varFilter.

+.SH DESCRIPTION
+.PP
+Samtools is a set of utilities that manipulate alignments in the BAM
+format. It imports from and exports to the SAM (Sequence Alignment/Map)
+format, does sorting, merging and indexing, and allows to retrieve reads
+in any regions swiftly.
+
+Samtools is designed to work on a stream. It regards an input file `-'
+as the standard input (stdin) and an output file `-' as the standard
+output (stdout). Several commands can thus be combined with Unix
+pipes. Samtools always output warning and error messages to the standard
+error output (stderr).
+
+Samtools is also able to open a BAM (not SAM) file on a remote FTP or
+HTTP server if the BAM file name starts with `ftp://' or `http://'.
+Samtools checks the current working directory for the index file and
+will download the index upon absence. Samtools does not retrieve the
+entire alignment file unless it is asked to do so.
+
+.SH COMMANDS AND OPTIONS
+
+.TP 10
+.B view
+samtools view [-bchuHS] [-t in.refList] [-o output] [-f reqFlag] [-F
+skipFlag] [-q minMapQ] [-l library] [-r readGroup] [-R rgFile] <in.bam>|<in.sam> [region1 [...]]
+
+Extract/print all or sub alignments in SAM or BAM format. If no region
+is specified, all the alignments will be printed; otherwise only
+alignments overlapping the specified regions will be output. An
+alignment may be given multiple times if it is overlapping several
+regions. A region can be presented, for example, in the following
+format: `chr2' (the whole chr2), `chr2:1000000' (region starting from
+1,000,000bp) or `chr2:1,000,000-2,000,000' (region between 1,000,000 and
+2,000,000bp including the end points). The coordinate is 1-based.
+
+.B OPTIONS:
+.RS
+.TP 8
+.B -b
+Output in the BAM format.
+.TP
+.BI -f \ INT
+Only output alignments with all bits in INT present in the FLAG
+field. INT can be in hex in the format of /^0x[0-9A-F]+/ [0]
+.TP
+.BI -F \ INT
+Skip alignments with bits present in INT [0]
+.TP
+.B -h
+Include the header in the output.
+.TP
+.B -H
+Output the header only.
+.TP
+.BI -l \ STR
+Only output reads in library STR [null]
+.TP
+.BI -o \ FILE
+Output file [stdout]
+.TP
+.BI -q \ INT
+Skip alignments with MAPQ smaller than INT [0]
+.TP
+.BI -r \ STR
+Only output reads in read group STR [null]
+.TP
+.BI -R \ FILE
+Output reads in read groups listed in
+.I FILE
+[null]
+.TP
+.B -S
+Input is in SAM. If @SQ header lines are absent, the
+.B `-t'
+option is required.
+.TP
+.B -c
+Instead of printing the alignments, only count them and print the
+total number. All filter options, such as
+.B `-f',
+.B `-F'
+and
+.B `-q'
+, are taken into account.
+.TP
+.BI -t \ FILE
+This file is TAB-delimited. Each line must contain the reference name
+and the length of the reference, one line for each distinct reference;
+additional fields are ignored. This file also defines the order of the
+reference sequences in sorting. If you run `samtools faidx <ref.fa>',
+the resultant index file
+.I <ref.fa>.fai
+can be used as this
+.I <in.ref_list>
+file.
+.TP
+.B -u
+Output uncompressed BAM. This option saves time spent on
+compression/decomprssion and is thus preferred when the output is piped
+to another samtools command.
+.RE
+
+.TP
+.B tview
+samtools tview <in.sorted.bam> [ref.fasta]
+
+Text alignment viewer (based on the ncurses library). In the viewer,
+press `?' for help and press `g' to check the alignment start from a
+region in the format like `chr10:10,000,000' or `=10,000,000' when
+viewing the same reference sequence.
+
+.TP
+.B mpileup
+samtools mpileup [-EBug] [-C capQcoef] [-r reg] [-f in.fa] [-l list] [-M capMapQ] [-Q minBaseQ] [-q minMapQ] in.bam [in2.bam [...]]
+
+Generate BCF or pileup for one or multiple BAM files. Alignment records
+are grouped by sample identifiers in @RG header lines. If sample
+identifiers are absent, each input file is regarded as one sample.
+
+.B OPTIONS:
+.RS
+.TP 10
+.B -A
+Do not skip anomalous read pairs in variant calling.
+.TP
+.B -B
+Disable probabilistic realignment for the computation of base alignment
+quality (BAQ). BAQ is the Phred-scaled probability of a read base being
+misaligned. Applying this option greatly helps to reduce false SNPs
+caused by misalignments.
+.TP
+.BI -C \ INT
+Coefficient for downgrading mapping quality for reads containing
+excessive mismatches. Given a read with a phred-scaled probability q of
+being generated from the mapped position, the new mapping quality is
+about sqrt((INT-q)/INT)*INT. A zero value disables this
+functionality; if enabled, the recommended value for BWA is 50. [0]
+.TP
+.BI -d \ INT
+At a position, read maximally
+.I INT
+reads per input BAM. [250]
+.TP
+.B -D
+Output per-sample read depth
+.TP
+.BI -e \ INT
+Phred-scaled gap extension sequencing error probability. Reducing
+.I INT
+leads to longer indels. [20]
+.TP
+.B -E
+Extended BAQ computation. This option helps sensitivity especially for MNPs, but may hurt
+specificity a little bit.
+.TP
+.BI -f \ FILE
+The reference file [null]
+.TP
+.B -g
+Compute genotype likelihoods and output them in the binary call format (BCF).
+.TP
+.BI -h \ INT
+Coefficient for modeling homopolymer errors. Given an
+.IR l -long
+homopolymer
+run, the sequencing error of an indel of size
+.I s
+is modeled as
+.IR INT * s / l .
+[100]
+.TP
+.B -I
+Do not perform INDEL calling
+.TP
+.BI -l \ FILE
+File containing a list of sites where pileup or BCF is outputted [null]
+.TP
+.BI -L \ INT
+Skip INDEL calling if the average per-sample depth is above
+.IR INT .
+[250]
+.TP
+.BI -o \ INT
+Phred-scaled gap open sequencing error probability. Reducing
+.I INT
+leads to more indel calls. [40]
+.TP
+.BI -P \ STR
+Comma dilimited list of platforms (determined by
+.BR @RG-PL )
+from which indel candidates are obtained. It is recommended to collect
+indel candidates from sequencing technologies that have low indel error
+rate such as ILLUMINA. [all]
+.TP
+.BI -q \ INT
+Minimum mapping quality for an alignment to be used [0]
+.TP
+.BI -Q \ INT
+Minimum base quality for a base to be considered [13]
+.TP
+.BI -r \ STR
+Only generate pileup in region
+.I STR
+[all sites]
+.TP
+.B -S
+Output per-sample Phred-scaled strand bias P-value
+.TP
+.B -u
+Similar to
+.B -g
+except that the output is uncompressed BCF, which is preferred for piping.
+.RE
+
+.TP
+.B reheader
+samtools reheader <in.header.sam> <in.bam>
+
+Replace the header in
+.I in.bam
+with the header in
+.I in.header.sam.
+This command is much faster than replacing the header with a
+BAM->SAM->BAM conversion.
+
+.TP
+.B cat
+samtools cat [-h header.sam] [-o out.bam] <in1.bam> <in2.bam> [ ... ]
+
+Concatenate BAMs. The sequence dictionary of each input BAM must be identical,
+although this command does not check this. This command uses a similar trick
+to
+.B reheader
+which enables fast BAM concatenation.
+
+.TP
+.B sort
+samtools sort [-no] [-m maxMem] <in.bam> <out.prefix>
+
+Sort alignments by leftmost coordinates. File
+.I <out.prefix>.bam
+will be created. This command may also create temporary files
+.I <out.prefix>.%d.bam
+when the whole alignment cannot be fitted into memory (controlled by
+option -m).
+
+.B OPTIONS:
+.RS
+.TP 8
+.B -o
+Output the final alignment to the standard output.
+.TP
+.B -n
+Sort by read names rather than by chromosomal coordinates
+.TP
+.BI -m \ INT
+Approximately the maximum required memory. [500000000]
+.RE
+
+.TP
+.B merge
+samtools merge [-nur1f] [-h inh.sam] [-R reg] <out.bam> <in1.bam> <in2.bam> [...]
+
+Merge multiple sorted alignments.
+The header reference lists of all the input BAM files, and the @SQ headers of
+.IR inh.sam ,
+if any, must all refer to the same set of reference sequences.
+The header reference list and (unless overridden by
+.BR -h )
+`@' headers of
+.I in1.bam
+will be copied to
+.IR out.bam ,
+and the headers of other files will be ignored.
+
+.B OPTIONS:
+.RS
+.TP 8
+.B -1
+Use zlib compression level 1 to comrpess the output
+.TP
+.B -f
+Force to overwrite the output file if present.
+.TP 8
+.BI -h \ FILE
+Use the lines of
+.I FILE
+as `@' headers to be copied to
+.IR out.bam ,
+replacing any header lines that would otherwise be copied from
+.IR in1.bam .
+.RI ( FILE
+is actually in SAM format, though any alignment records it may contain
+are ignored.)
+.TP
+.B -n
+The input alignments are sorted by read names rather than by chromosomal
+coordinates
+.TP
+.BI -R \ STR
+Merge files in the specified region indicated by
+.I STR
+[null]
+.TP
+.B -r
+Attach an RG tag to each alignment. The tag value is inferred from file names.
+.TP
+.B -u
+Uncompressed BAM output
+.RE
+
+.TP
+.B index
+samtools index <aln.bam>
+
+Index sorted alignment for fast random access. Index file
+.I <aln.bam>.bai
+will be created.
+
+.TP
+.B idxstats
+samtools idxstats <aln.bam>
+
+Retrieve and print stats in the index file. The output is TAB delimited
+with each line consisting of reference sequence name, sequence length, #
+mapped reads and # unmapped reads.
+
+.TP
+.B faidx
+samtools faidx <ref.fasta> [region1 [...]]
+
+Index reference sequence in the FASTA format or extract subsequence from
+indexed reference sequence. If no region is specified,
+.B faidx
+will index the file and create
+.I <ref.fasta>.fai
+on the disk. If regions are speficified, the subsequences will be
+retrieved and printed to stdout in the FASTA format. The input file can
+be compressed in the
+.B RAZF
+format.
+
+.TP
+.B fixmate
+samtools fixmate <in.nameSrt.bam> <out.bam>
+
+Fill in mate coordinates, ISIZE and mate related flags from a
+name-sorted alignment.
+
+.TP
+.B rmdup
+samtools rmdup [-sS] <input.srt.bam> <out.bam>
+
+Remove potential PCR duplicates: if multiple read pairs have identical
+external coordinates, only retain the pair with highest mapping quality.
+In the paired-end mode, this command
+.B ONLY
+works with FR orientation and requires ISIZE is correctly set. It does
+not work for unpaired reads (e.g. two ends mapped to different
+chromosomes or orphan reads).
+
+.B OPTIONS:
+.RS
+.TP 8
+.B -s
+Remove duplicate for single-end reads. By default, the command works for
+paired-end reads only.
+.TP 8
+.B -S
+Treat paired-end reads and single-end reads.
+.RE
+
+.TP
+.B calmd
+samtools calmd [-EeubSr] [-C capQcoef] <aln.bam> <ref.fasta>
+
+Generate the MD tag. If the MD tag is already present, this command will
+give a warning if the MD tag generated is different from the existing
+tag. Output SAM by default.
+
+.B OPTIONS:
+.RS
+.TP 8
+.B -A
+When used jointly with
+.B -r
+this option overwrites the original base quality.
+.TP 8
+.B -e
+Convert a the read base to = if it is identical to the aligned reference
+base. Indel caller does not support the = bases at the moment.
+.TP
+.B -u
+Output uncompressed BAM
+.TP
+.B -b
+Output compressed BAM
+.TP
+.B -S
+The input is SAM with header lines
+.TP
+.BI -C \ INT
+Coefficient to cap mapping quality of poorly mapped reads. See the
+.B pileup
+command for details. [0]

+
+Print the alignment in the pileup format. In the pileup format, each
+line represents a genomic position, consisting of chromosome name,
+coordinate, reference base, read bases, read qualities and alignment
+mapping qualities. Information on match, mismatch, indel, strand,
+mapping quality and start and end of a read are all encoded at the read
+base column. At this column, a dot stands for a match to the reference
+base on the forward strand, a comma for a match on the reverse strand,
+a '>' or '<' for a reference skip, `ACGTN' for a mismatch on the forward
+strand and `acgtn' for a mismatch on the reverse strand. A pattern
+`\\+[0-9]+[ACGTNacgtn]+' indicates there is an insertion between this
+reference position and the next reference position. The length of the
+insertion is given by the integer in the pattern, followed by the
+inserted sequence. Similarly, a pattern `-[0-9]+[ACGTNacgtn]+'
+represents a deletion from the reference. The deleted bases will be
+presented as `*' in the following lines. Also at the read base column, a
+symbol `^' marks the start of a read. The ASCII of the character
+following `^' minus 33 gives the mapping quality. A symbol `$' marks the
+end of a read segment.
+
+If option
+.B -c
+is applied, the consensus base, Phred-scaled consensus quality, SNP
+quality (i.e. the Phred-scaled probability of the consensus being
+identical to the reference) and root mean square (RMS) mapping quality
+of the reads covering the site will be inserted between the `reference
+base' and the `read bases' columns. An indel occupies an additional
+line. Each indel line consists of chromosome name, coordinate, a star,
+the genotype, consensus quality, SNP quality, RMS mapping quality, #
+covering reads, the first alllele, the second allele, # reads supporting
+the first allele, # reads supporting the second allele and # reads
+containing indels different from the top two alleles.

+.SH EXAMPLES
+.IP o 2
+Import SAM to BAM when
+.B @SQ
+lines are present in the header:
+
+  samtools view -bS aln.sam > aln.bam
+
+If
+.B @SQ
+lines are absent:
+
+  samtools faidx ref.fa
+  samtools view -bt ref.fa.fai aln.sam > aln.bam
+
+where
+.I ref.fa.fai
+is generated automatically by the
+.B faidx
+command.
+
+.IP o 2
+Attach the
+.B RG
+tag while merging sorted alignments:
+
+  perl -e 'print "@RG\\tID:ga\\tSM:hs\\tLB:ga\\tPL:Illumina\\n@RG\\tID:454\\tSM:hs\\tLB:454\\tPL:454\\n"' > rg.txt
+  samtools merge -rh rg.txt merged.bam ga.bam 454.bam
+
+The value in a
+.B RG
+tag is determined by the file name the read is coming from. In this
+example, in the
+.IR merged.bam ,
+reads from
+.I ga.bam
+will be attached 
+.IR RG:Z:ga ,
+while reads from
+.I 454.bam
+will be attached
+.IR RG:Z:454 .
+
+.IP o 2
+Call SNPs and short indels for one diploid individual:
+
+  samtools mpileup -ugf ref.fa aln.bam | bcftools view -bvcg - > var.raw.bcf
+  bcftools view var.raw.bcf | vcfutils.pl varFilter -D 100 > var.flt.vcf
+
+The
+.B -D
+option of varFilter controls the maximum read depth, which should be
+adjusted to about twice the average read depth.  One may consider to add
+.B -C50
+to
+.B mpileup
+if mapping quality is overestimated for reads containing excessive
+mismatches. Applying this option usually helps
+.B BWA-short
+but may not other mappers.
+
+.IP o 2
+Generate the consensus sequence for one diploid individual:
+
+  samtools mpileup -uf ref.fa aln.bam | bcftools view -cg - | vcfutils.pl vcf2fq > cns.fq
+
+.IP o 2
+Phase one individual:
+
+  samtools calmd -AEur aln.bam ref.fa | samtools phase -b prefix - > phase.out
+
+The
+.B calmd
+command is used to reduce false heterozygotes around INDELs.
+
+.IP o 2
+Call SNPs and short indels for multiple diploid individuals:
+
+  samtools mpileup -P ILLUMINA -ugf ref.fa *.bam | bcftools view -bcvg - > var.raw.bcf
+  bcftools view var.raw.bcf | vcfutils.pl varFilter -D 2000 > var.flt.vcf
+
+Individuals are identified from the
+.B SM
+tags in the
+.B @RG
+header lines. Individuals can be pooled in one alignment file; one
+individual can also be separated into multiple files. The
+.B -P
+option specifies that indel candidates should be collected only from
+read groups with the
+.B @RG-PL
+tag set to
+.IR ILLUMINA .
+Collecting indel candidates from reads sequenced by an indel-prone
+technology may affect the performance of indel calling.
+
+.IP o 2
+Derive the allele frequency spectrum (AFS) on a list of sites from multiple individuals:
+
+  samtools mpileup -Igf ref.fa *.bam > all.bcf
+  bcftools view -bl sites.list all.bcf > sites.bcf
+  bcftools view -cGP cond2 sites.bcf > /dev/null 2> sites.1.afs
+  bcftools view -cGP sites.1.afs sites.bcf > /dev/null 2> sites.2.afs
+  bcftools view -cGP sites.2.afs sites.bcf > /dev/null 2> sites.3.afs
+  ......
+
+where
+.I sites.list
+contains the list of sites with each line consisting of the reference
+sequence name and position. The following
+.B bcftools
+commands estimate AFS by EM.
+
+.IP o 2
+Dump BAQ applied alignment for other SNP callers:
+
+  samtools calmd -bAr aln.bam > aln.baq.bam
+
+It adds and corrects the
+.B NM
+and
+.B MD
+tags at the same time. The
+.B calmd
+command also comes with the
+.B -C
+option, the same as the one in
+.B pileup
+and
+.BR mpileup .
+Apply if it helps.
+
+.SH LIMITATIONS
+.PP
+.IP o 2
+Unaligned words used in bam_import.c, bam_endian.h, bam.c and bam_aux.c.
+.IP o 2
+In merging, the input files are required to have the same number of
+reference sequences. The requirement can be relaxed. In addition,
+merging does not reconstruct the header dictionaries
+automatically. Endusers have to provide the correct header. Picard is
+better at merging.
+.IP o 2
+Samtools paired-end rmdup does not work for unpaired reads (e.g. orphan
+reads or ends mapped to different chromosomes). If this is a concern,
+please use Picard's MarkDuplicate which correctly handles these cases,
+although a little slower.

+PDCurses Text Attributes
+========================
+
+Originally, PDCurses used a short (16 bits) for its chtype. To include 
+color, a number of things had to be sacrificed from the strict Unix and 
+System V support. The main problem was fitting all character attributes 
+and color into an unsigned char (all 8 bits!).
+
+Today, PDCurses by default uses a long (32 bits) for its chtype, as in 
+System V. The short chtype is still available, by undefining CHTYPE_LONG 
+and rebuilding the library.
+
+The following is the structure of a win->_attrs chtype:
+
+short form:
+
+-------------------------------------------------
+|15|14|13|12|11|10| 9| 8| 7| 6| 5| 4| 3| 2| 1| 0|
+-------------------------------------------------
+  color number |  attrs |   character eg 'a'
+
+The available non-color attributes are bold, reverse and blink. Others 
+have no effect. The high order char is an index into an array of 
+physical colors (defined in color.c) -- 32 foreground/background color 
+pairs (5 bits) plus 3 bits for other attributes.
+
+long form:
+
+----------------------------------------------------------------------------
+|31|30|29|28|27|26|25|24|23|22|21|20|19|18|17|16|15|14|13|12|..| 3| 2| 1| 0|
+----------------------------------------------------------------------------
+      color number      |     modifiers         |      character eg 'a'
+
+The available non-color attributes are bold, underline, invisible, 
+right-line, left-line, protect, reverse and blink. 256 color pairs (8 
+bits), 8 bits for other attributes, and 16 bits for character data.

+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+     This library can optionally read and write gzip streams in memory as well.
+
+     The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumualte before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  the value returned by deflateBound (see below). If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible
+  (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows. inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing
+    will resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there
+    is no more input data or no more space in the output buffer (see below
+    about the flush parameter).
+
+  Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (avail_out == 0), or after each
+  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+  must be called again after making room in the output buffer because there
+  might be more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+  Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+  if and when it gets to the next deflate block boundary. When decoding the
+  zlib or gzip format, this will cause inflate() to return immediately after
+  the header and before the first block. When doing a raw inflate, inflate()
+  will go ahead and process the first block, and will return when it gets to
+  the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64
+  if inflate() is currently decoding the last block in the deflate stream,
+  plus 128 if inflate() returned immediately after decoding an end-of-block
+  code or decoding the complete header up to just before the first byte of the
+  deflate stream. The end-of-block will not be indicated until all of the
+  uncompressed data from that block has been written to strm->next_out.  The
+  number of unused bits may in general be greater than seven, except when
+  bit 7 of data_type is set, in which case the number of unused bits will be
+  less than eight.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster approach
+  may be used for the single inflate() call.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call. So the only effect of the flush parameter in this implementation
+  is on the return value of inflate(), as noted below, or when it returns early
+  because Z_BLOCK is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the adler32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the adler32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below. At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically.  Any information
+  contained in the gzip header is not retained, so applications that need that
+  information should instead use raw inflate, see inflateInit2() below, or
+  inflateBack() and perform their own processing of the gzip header and

+
+     This is another version of deflateInit with more compression options. The
+   fields next_in, zalloc, zfree and opaque must be initialized before by
+   the caller.
+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer). It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+   determines the window size. deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute an adler32 check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding. Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper. The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero),
+   no header crc, and the operating system will be set to 255 (unknown).  If a
+   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding). Filtered data consists mostly of small values with a somewhat
+   random distribution. In this case, the compression algorithm is tuned to
+   compress them better. The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as
+   Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy
+   parameter only affects the compression ratio but not the correctness of the
+   compressed output even if it is not set appropriately.  Z_FIXED prevents the
+   use of dynamic Huffman codes, allowing for a simpler decoder for special
+   applications.
+
+      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
+   method). msg is set to null if there is no error message.  deflateInit2 does

+   dictionary (see inflateSetDictionary).
+
+     The dictionary should consist of strings (byte sequences) that are likely
+   to be encountered later in the data to be compressed, with the most commonly
+   used strings preferably put towards the end of the dictionary. Using a
+   dictionary is most useful when the data to be compressed is short and can be

+   discarded, for example if the dictionary is larger than the window size in
+   deflate or deflate2. Thus the strings most likely to be useful should be

+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero--buf is ignored in that
+   case--and inflateBack() will return a buffer error.  inflateBack() will call
+   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
+   should return zero on success, or non-zero on failure.  If out() returns
+   non-zero, inflateBack() will return with an error.  Neither in() nor out()
+   are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format
+   error in the deflate stream (in which case strm->msg is set to indicate the
+   nature of the error), or Z_STREAM_ERROR if the stream was not properly
+   initialized.  In the case of Z_BUF_ERROR, an input or output error can be
+   distinguished using strm->next_in which will be Z_NULL only if in() returned
+   an error.  If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to
+   out() returning non-zero.  (in() will always be called before out(), so
+   strm->next_in is assured to be defined if out() returns non-zero.)  Note
+   that inflateBack() cannot return Z_OK.
