Prokka wrapper
==============

Warning
-------

Prokka includes custom databases and is thus about a 2.0 GB download!

Dependencies of Prokka which needs to be installed separately
-------------------------------------------------------------

- Perl core modules: File\::Copy, FindBin, Getopt::Long, List::Util, Scalar::Util, Time::Piece, Time::Seconds;
- Perl modules: Bio::SeqIO from BioPerl_ >= 1.6.900, `XML::Simple`_;
- SignalP_ >= 3.0 is an optional dependency to find signal peptides. For licensing reasons, it is not used in the tool wrapper.

.. _BioPerl: http://search.cpan.org/dist/BioPerl/
.. _XML::Simple: http://search.cpan.org/dist/XML-Simple/
.. _SignalP: http://www.cbs.dtu.dk/services/SignalP/

Configuration
-------------

prokka tool may be configured to use more than one CPU core by selecting an appropriate destination for this tool in Galaxy job_conf.xml file (see http://wiki.galaxyproject.org/Admin/Config/Jobs and http://wiki.galaxyproject.org/Admin/Config/Performance/Cluster ).

If you are using Galaxy release_2013.11.04 or later, this tool will automatically use the number of CPU cores allocated by the job runner according to the configuration of the destination selected for this tool.

If instead you are using an older Galaxy release, you should also add a line

  GALAXY_SLOTS=N; export GALAXY_SLOTS

(where N is the number of CPU cores allocated by the job runner for this tool) to the file

  <tool_dependencies_dir>/prokka/1.7/crs4/prokka/<hash_string>/env.sh
