glam2 - Gapped Local Alignment of Motifs

glam2 [options] alphabet my_seqs.fa

An alphabet other than p or n is interpreted as the name of an alphabet file.

GLAM2 is a software package for finding motifs in sequences, typically amino-acid or nucleotide sequences. A motif is a re-occurring sequence pattern: typical examples are the TATA box and the CAAX prenylation motif. The main innovation of GLAM2 is that it allows insertions and deletions in motifs.
