NAME ^

Bio::SearchIO::psl - A parser for PSL output (UCSC)

SYNOPSIS ^

  use Bio::SearchIO;
  my $parser = Bio::SearchIO->new(-file   => 'file.psl',
                                 -format => 'psl');
  while( my $result = $parser->next_result ) {
  }

DESCRIPTION ^

This is a SearchIO driver for PSL format. PSL format is documented here: http://genome.ucsc.edu/goldenPath/help/customTrack.html#PSL

By default it assumes PSL output came from BLAT you can override that by specifying -program_name => 'BLASTZ' when initializing the SearchIO object.
