Bio::Tools::EMBOSS::Palindrome - parse EMBOSS palindrome output


  # a simple script to turn palindrome output into GFF3
  use Bio::Tools::EMBOSS::Palindrome;
  use Bio::Tools::GFF;
  my $parser = Bio::Tools::EMBOSS::Palindrome->new(-file => $filename);
  my $out    = Bio::Tools::GFF->new(-gff_version => 3,
                                   -file => ">$filename.gff");
  while( my $seq = $parser->next_seq ) {
     for my $feat ( $seq->get_SeqFeatures ) {


This is a parser for the EMBOSS tool 'palindrome'. It will produce a Bio::Seq object for each sequence analyzed. The sequence will be empty (but will be of the correct length) and will have attached to it Bio::SeqFeature::FeaturePair objects which wil


It may be consolidated into another framework at a later time, but for the time being it will stay a separate modules.
