## BUGS:
$bugs = "New features in this version ($app_version):\
- None\
\
Fixed bugs in this version ($app_version):\
- Fixed a bug causing newline characters to be occasionally skipped in the 'its1.full_and_partial.fasta' FASTA output file when the '--anchor' option was used\
\
Known bugs in this version ($app_version):\
- None\
";

## OPTIONS:
$options = "\
-i {file} : DNA FASTA input file to investigate\
-o {file} : Base for the names of output file(s)\
-p {directory} : A path to a directory of HMM-profile collections representing ITS conserved regions, default is in the same directory as ITSx itself\
--date {T or F} : Adds a date and time stamp to the output directory, off (F) by default\
--reset {T or F} : Re-creates the HMM-database before ITSx is run, off (F) by default\

Sequence selection options:\
-t {character code} : Profile set to use for the search, see the User's Guide (comma-separated), default is all\
-E {value} : Domain E-value cutoff for a sequence to be included in the output, default = 1e-5\
-S {value} : Domain score cutoff for a sequence to be included in the output, default = 0\
-N {value} : The minimal number of domains that must match a sequence before it is included, default = 2\
--selection_priority {sum, domains, eval, score} : Selects what will be of highest priority when determining the origin of the sequence, default is sum\
--search_eval {value} : The E-value cutoff used in the HMMER search, high numbers may slow down the process, cannot be used with the --search_score option, default is 0.01\
--search_score {value} : The score cutoff used in the HMMER search, low numbers may slow down the process, cannot be used with the --search_eval option, default is to used E-value cutoff, not score\
--allow_single_domain {e-value,score or F} : Allow inclusion of sequences that only find a single domain, given that they meet the given E-value and score thresholds, on with parameters 1e-9,0 by default\
--allow_reorder {T or F} : Allows profiles to be in the wrong order on extracted sequences, off (F) by default\
--complement {T or F} : Checks both DNA strands against the database, creating reverse complements, on (T) by default\
--cpu {value} : the number of CPU threads to use, default is 1\
--multi_thread {T or F} : Multi-thread the HMMER-search, on (T) if number of CPUs (--cpu option > 1), else off (F) by default\

Output options:\
--summary {T or F} : Summary of results output, on (T) by default\
--graphical {T or F} : 'Graphical' output, on (T) by default\
--fasta {T or F} : FASTA-format output of extracted ITS sequences, on (T) by default\

--anchor {integer or HMM} : Saves an additional number of bases before and after each extracted region. If set to 'HMM' all bases matching the corresponding HMM will be output, default = 0\
--only_full {T or F} : If true, output is limited to full-length regions, off (F) by default\
--partial {integer} : Saves additional FASTA-files for full and partial ITS sequences longer than the specified cutoff, default = 0 (off)\
--concat {T or F} : Saves a FASTA-file with concatenated ITS sequences (with 5.8S removed), off (F) by default\
--minlen {integer} : Minimum length the ITS regions must be to be outputted in the concatenated file (see above), default = 0\
--positions {T or F} : Table format output containing the positions ITS sequences were found in, on (T) by default\
