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.

FEEDBACK ^

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.
