%description

Bowtie 2 is an ultra fast and memory-efficient tool for aligning sequencing
reads to long reference sequences. It is particularly good at aligning reads
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.
