[PATCH] gnu: Add bowtie.

[Ricardo Wurmus <ricardo.wurmus@mdc-berlin.de>]

[-- Attachment #1: Type: text/plain, Size: 428 bytes --]

Attached is a patch to add bowtie to the bioinformatics module.  The
test suite depends on a couple of Perl modules for which I have
previously submitted patches:

- [[http://lists.gnu.org/archive/html/guix-devel/2014-12/msg00326.html][Test::Simple]]
- [[http://lists.gnu.org/archive/html/guix-devel/2014-12/msg00321.html][Test::Deep]]
- [[http://lists.gnu.org/archive/html/guix-devel/2014-12/msg00323.html][Clone]]

+of about 50 up to 100s or 1,000s of characters, and particularly good at
+aligning to relatively long (e.g. mammalian) genomes.  Bowtie 2 indexes the
+genome with an FM Index to keep its memory footprint small: for the human
+genome, its memory footprint is typically around 3.2 GB.  Bowtie 2 supports
+gapped, local, and paired-end alignment modes.")
