Bio::Tools::Promoterwise - parser for Promoterwise tab format output


  use Bio::Tools::Promoterwise;
  my $pw = Bio::Tools::Promoterwise->new(-file=>"out",
  while (my $fp = $pw->next_result){
    print "Hit Length: ".$fp->feature1->length."\n";
    print "Hit Start: ".$fp->feature1->start."\n";
    print "Hit End: ".$fp->feature1->end."\n";
    print "Hsps: \n";
    my @first_hsp = $fp->feature1->sub_SeqFeature;
    my @second_hsp = $fp->feature2->sub_SeqFeature;
    foreach my $i (0..$#first_hsp){
      print $first_hsp[$i]->start. " ".$first_hsp[$i]->end." ".
            $second_hsp[$i]->start. " ".$second_hsp[$i]->end."\n";


Promoteriwise is an alignment algorithm that relaxes the constraint that local alignments have to be co-linear. Otherwise it provides a similar model to DBA, which is designed for promoter sequence alignments. Promoterwise is written by Ewan Birney. It is part of the wise2 package available at <>

This module is the parser for the Promoterwise output in tab format.
