NAME

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

SYNOPSIS

use FAST::Bio::SearchIO;
my $parser = FAST::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.
