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  - Cope with samtools' default depth limit using modified samtools,
          see https://github.com/samtools/samtools/pull/322
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  - Python 3 compatibility fix.
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
    ...
