14 **Short Story**
|
|
|
15
|
|
|
16 This is an unusual Galaxy tool capable of generating new Galaxy tools.
|
|
|
17 It works by exposing *unrestricted* and therefore extremely dangerous scripting
|
|
|
18 to all designated administrators of the host Galaxy server, allowing them to
|
|
|
19 run scripts in R, python, sh and perl over multiple selected input data sets,
|
|
|
20 writing a single new data set as output.
|
|
|
21
|
|
|
22 *You have a working r/python/perl/bash script or any executable with positional or argparse style parameters*
|
|
|
23
|
|
|
24 It can be turned into an ordinary Galaxy tool in minutes, using a Galaxy tool.
|
|
|
25
|
|
|
26
|
|
|
27 **Automated generation of new Galaxy tools for installation into any Galaxy**
|
|
|
28
|
|
|
29 A test is generated using small sample test data inputs and parameter settings you supply.
|
|
|
30 Once the test case outputs have been produced, they can be used to build a
|
|
|
31 new Galaxy tool. The supplied script or executable is baked as a requirement
|
|
|
32 into a new, ordinary Galaxy tool, fully workflow compatible out of the box.
|
|
|
33 Generated tools are installed via a tool shed by an administrator
|
|
|
34 and work exactly like all other Galaxy tools for your users.
|
|
|
35
|
|
|
36 **More Detail**
|
|
|
37
|
|
|
38 To use the ToolFactory, you should have prepared a script to paste into a
|
|
|
39 text box, or have a package in mind and a small test input example ready to select from your history
|
|
|
40 to test your new script.
|
|
|
41
|
|
|
42 ```planemo test rgToolFactory2.xml --galaxy_root ~/galaxy --test_data ~/galaxy/tools/tool_makers/toolfactory/test-data``` works for me
|
|
|
43
|
|
|
44 There is an example in each scripting language on the Tool Factory form. You
|
|
|
45 can just cut and paste these to try it out - remember to select the right
|
|
|
46 interpreter please. You'll also need to create a small test data set using
|
|
|
47 the Galaxy history add new data tool.
|
|
|
48
|
|
|
49 If the script fails somehow, use the "redo" button on the tool output in
|
|
|
50 your history to recreate the form complete with broken script. Fix the bug
|
|
|
51 and execute again. Rinse, wash, repeat.
|
|
|
52
|
|
|
53 Once the script runs sucessfully, a new Galaxy tool that runs your script
|
|
|
54 can be generated. Select the "generate" option and supply some help text and
|
|
|
55 names. The new tool will be generated in the form of a new Galaxy datatype
|
|
|
56 *toolshed.gz* - as the name suggests, it's an archive ready to upload to a
|
|
|
57 Galaxy ToolShed as a new tool repository.
|
|
|
58
|
|
|
59 Once it's in a ToolShed, it can be installed into any local Galaxy server
|
|
|
60 from the server administrative interface.
|
|
|
61
|
|
|
62 Once the new tool is installed, local users can run it - each time, the script
|
|
|
63 that was supplied when it was built will be executed with the input chosen
|
|
|
64 from the user's history. In other words, the tools you generate with the
|
|
|
65 ToolFactory run just like any other Galaxy tool,but run your script every time.
|
|
|
66
|
|
|
67 Tool factory tools are perfect for workflow components. One input, one output,
|
|
|
68 no variables.
|
|
|
69
|
|
|
70 *To fully and safely exploit the awesome power* of this tool,
|
|
|
71 Galaxy and the ToolShed, you should be a developer installing this
|
|
|
72 tool on a private/personal/scratch local instance where you are an
|
|
|
73 admin_user. Then, if you break it, you get to keep all the pieces see
|
|
|
74 https://bitbucket.org/fubar/galaxytoolfactory/wiki/Home
|
|
|
75
|
|
|
76 **Installation**
|
|
|
77 This is a Galaxy tool. You can install it most conveniently using the
|
|
|
78 administrative "Search and browse tool sheds" link. Find the Galaxy Main
|
|
|
79 toolshed at https://toolshed.g2.bx.psu.edu/ and search for the toolfactory
|
|
|
80 repository. Open it and review the code and select the option to install it.
|
|
|
81
|
|
|
82 If you can't get the tool that way, the xml and py files here need to be
|
|
|
83 copied into a new tools
|
|
|
84 subdirectory such as tools/toolfactory Your tool_conf.xml needs a new entry
|
|
|
85 pointing to the xml
|
|
|
86 file - something like::
|
|
|
87
|
|
|
88 <section name="Tool building tools" id="toolbuilders">
|
|
|
89 <tool file="toolfactory/rgToolFactory.xml"/>
|
|
|
90 </section>
|
|
|
91
|
|
|
92 If not already there,
|
|
|
93 please add:
|
|
|
94 <datatype extension="toolshed.gz" type="galaxy.datatypes.binary:Binary"
|
|
|
95 mimetype="multipart/x-gzip" subclass="True" />
|
|
|
96 to your local data_types_conf.xml.
|
|
|
97
|
|
|
98
|
|
|
99 **Restricted execution**
|
|
|
100
|
|
|
101 The tool factory tool itself will then be usable ONLY by admin users -
|
|
|
102 people with IDs in admin_users in universe_wsgi.ini **Yes, that's right. ONLY
|
|
|
103 admin_users can run this tool** Think about it for a moment. If allowed to
|
|
|
104 run any arbitrary script on your Galaxy server, the only thing that would
|
|
|
105 impede a miscreant bent on destroying all your Galaxy data would probably
|
|
|
106 be lack of appropriate technical skills.
|
|
|
107
|
|
|
108 **What it does**
|
|
|
109
|
|
|
110 This is a tool factory for simple scripts in python, R and
|
|
|
111 perl currently. Functional tests are automatically generated. How cool is that.
|
|
|
112
|
|
|
113 LIMITED to simple scripts that read one input from the history. Optionally can
|
|
|
114 write one new history dataset, and optionally collect any number of outputs
|
|
|
115 into links on an autogenerated HTML index page for the user to navigate -
|
|
|
116 useful if the script writes images and output files - pdf outputs are shown
|
|
|
117 as thumbnails and R's bloated pdf's are shrunk with ghostscript so that and
|
|
|
118 imagemagik need to be available.
|
|
|
119
|
|
|
120 Generated tools can be edited and enhanced like any Galaxy tool, so start
|
|
|
121 small and build up since a generated script gets you a serious leg up to a
|
|
|
122 more complex one.
|
|
|
123
|
|
|
124 **What you do**
|
|
|
125
|
|
|
126 You paste and run your script, you fix the syntax errors and
|
|
|
127 eventually it runs. You can use the redo button and edit the script before
|
|
|
128 trying to rerun it as you debug - it works pretty well.
|
|
|
129
|
|
|
130 Once the script works on some test data, you can generate a toolshed compatible
|
|
|
131 gzip file containing your script ready to run as an ordinary Galaxy tool in
|
|
|
132 a repository on your local toolshed. That means safe and largely automated
|
|
|
133 installation in any production Galaxy configured to use your toolshed.
|
|
|
134
|
|
|
135 **Generated tool Security**
|
|
|
136
|
|
|
137 Once you install a generated tool, it's just
|
|
|
138 another tool - assuming the script is safe. They just run normally and their
|
|
|
139 user cannot do anything unusually insecure but please, practice safe toolshed.
|
|
|
140 Read the code before you install any tool. Especially this one - it is really scary.
|
|
|
