ruby-crb-blast binary package in Ubuntu Lunar amd64
CRB-BLAST is a novel method for finding orthologs between one set of sequences
and another. This is particularly useful in genome and transcriptome
annotation.
.
CRB-BLAST initially performs a standard reciprocal best BLAST. It does this by
performing BLAST alignments of query->target and target->query. Reciprocal
best BLAST hits are those where the best match for any given query sequence in
the query->target alignment is also the best hit of the match in the reverse
(target->query) alignment.
.
Reciprocal best BLAST is a very conservative way to assign orthologs. The main
innovation in CRB-BLAST is to learn an appropriate e-value cutoff to apply to
each pairwise alignment by taking into account the overall relatedness of the
two datasets being compared. This is done by fitting a function to the
distribution of alignment e-values over sequence lengths. The function
provides the e-value cutoff for a sequence of given length.
