gapped protein motifs from unaligned sequences

 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.
 .
 This package includes programs for discovering motifs shared by a set of
 sequences and finding matches to these motifs in a sequence database, as well
 as utilities for converting glam2 motifs to standard alignment formats,
 masking glam2 motifs out of sequences so that weaker motifs can be found, and
 removing highly similar members of a set of sequences.
 .
 The package includes these programs:
  glam2: discovering motifs shared by a set of sequences;
  glam2scan: finding matches, in a sequence database, to a motif discovered
               by glam2;
  glam2format: converting glam2 motifs to standard alignment formats;
  glam2mask: masking glam2 motifs out of sequences, so that weaker motifs
               can be found;
  glam2-purge: removing highly similar members of a set of sequences.
 .
 In this binary package, the fast Fourier algorithm (FFT) was enabled for the
 glam2 program.
