Synopsis: BAM coverage statistics using samtools idxstats and depth
This tool runs the commands ``samtools idxstats`` and ``samtools depth`` from

BAM coverage statistics using samtools idxstats and depth

This tool is copyright 2014-2017 by Peter Cock, The James Hutton Institute (formerly SCRI, Scottish Crop Research Institute), UK. All rights reserved. See the licence text below.

Internally this tool uses the command-line samtools suite.

This tool is available from the Galaxy Tool Shed at: http://toolshed.g2.bx.psu.edu/view/peterjc/coverage_stats

Automated Installation

This should be straightforward, provided your Galaxy is setup to use Conda and BioConda for dependencies - Galaxy should then automatically download and install the expected version of samtools.

Manual Installation

This expects samtools to be on the $PATH, and was tested using v1.3.1.

To install the wrapper copy or move the following files under the Galaxy tools folder, e.g. in a tools/coverage_stats folder:

  • coverage_stats.xml (the Galaxy tool definition)
  • coverage_stats.py (the Python wrapper script)
  • README.rst (this file)

You will also need to modify the tools_conf.xml file to tell Galaxy to offer the tool. Just add the line, perhaps under the NGS tools section:

<tool file="coverage_stats/coverage_stats.xml" />

If you wish to run the unit tests, also move/copy the test-data/ files under Galaxy's test-data/ folder. Then:

$ ./run_tests.sh -id coverage_stats

That's it.

History

Version Changes
v0.0.1
  • Initial public release
v0.0.2
v0.0.3
  • Cope with no coverage in final contigs.
v0.0.4
  • Reorder XML elements (internal change only).
  • Planemo for Tool Shed upload (.shed.yml, internal change only).
v0.0.5
  • Expose new samtools depth -d ... argument added in samtools v1.3
  • Depends on samtools v1.4.1 via Conda, which IS NOT AVAILABLE as a legacy Tool Shed package.
  • Apply the new maximum depth parameter within the script to ensure excess coverage is clear by getting the max coverage equal to the max depth setting (the raw output from samtools is more fuzzy).
  • Report total length and overall mean coverage in stdout.
  • Use <command detect_errors="aggressive"> (internal change only).
  • Single quote command line arguments (internal change only).
v0.0.6

v0.1.0
  • Provide proper command line API for the Python script.

Developers

Development is on this GitHub repository: https://github.com/peterjc/pico_galaxy/tree/master/tools/coverage_stats

For pushing a release to the test or main "Galaxy Tool Shed", use the following Planemo commands (which requires you have set your Tool Shed access details in ~/.planemo.yml and that you have access rights on the Tool Shed):

$ planemo shed_update -t testtoolshed --check_diff tools/coverage_stats/
...

or:

$ planemo shed_update -t toolshed --check_diff tools/coverage_stats/
...

To just build and check the tar ball, use:

$ planemo shed_upload --tar_only tools/coverage_stats/
...
$ tar -tzf shed_upload.tar.gz
tools/coverage_stats/README.rst
tools/coverage_stats/coverage_stats.xml
tools/coverage_stats/coverage_stats.py
...
