     "BEDOPS is a suite of tools to address common questions raised in genomic
studies---mostly with regard to overlap and proximity relationships between
data sets.  It aims to be scalable and flexible, facilitating the efficient
and accurate analysis and management of large-scale genomic data.

BEDOPS provides tools that perform highly efficient and scalable Boolean and
other set operations, statistical calculations, archiving, conversion and
other management of genomic data of arbitrary scale.  Tasks can be easily
split by chromosome for distributing whole-genome analyses across a
computational cluster.")

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.")

    (description
     "The Spliced Transcripts Alignment to a Reference (STAR) software is
based on a previously undescribed RNA-seq alignment algorithm that uses
sequential maximum mappable seed search in uncompressed suffix arrays followed
by seed clustering and stitching procedure.  In addition to unbiased de novo
detection of canonical junctions, STAR can discover non-canonical splices and
chimeric (fusion) transcripts, and is also capable of mapping full-length RNA
sequences.")
