NAME

Bio::Tools::Seg - parse seg output

SYNOPSIS

  use Bio::Tools::Seg;
  my $parser = Bio::Tools::Seg->(-file => 'seg.fasta');
  while ( my $f = $parser->next_result ) {
    if ($f->score < 1.5) {
      print $f->location->to_FTstring, " is low complexity\n";
    }
  }

DESCRIPTION

seg identifies low-complexity regions on a protein sequence. It is usually part of the WU-BLAST and InterProScan packages.

The Bio::Tools::Seg module will only parse the "fasta" output modes of seg, i.e. seg -l (low complexity regions only), seg -h (high complexity regions only), or seg -a (both low and high).

It creates a Bio::SeqFeature::Generic for each FASTA-like entry found in the input file. It is up to the user to appropriately filter these using the feature's score.
