NAME

       Bio::Tools::PrositeScan - Parser for ps_scan result

SYNOPSIS

         use Bio::Tools::PrositeScan;

         my $factory = Bio::Tools::PrositeScan->new(
             -file   => 'out.PrositeScan',
             -format => 'fasta'
         );

         while(my $match = $factory->next_prediction){
             #  $match is a Bio::SeqFeature::FeaturePair

             # Sequence ID
             my $seq_id = $match->seq_id;

             # PROSITE accession number
             my $psac = $match->hseq_id;

             # Coordinates
             my @coords = ( $match->start, $match->end );

             # Subsequence
             my $seq = $match->feature1->seq;
         }

DESCRIPTION

       This is a parser of the output of the ps_scan program. It takes either a file handle or a
       file name, and returns a Bio::SeqFeature::FeaturePair object.

       Note that the current implementation parses the entire file at once.

         Usage   : Bio::Tools::PrositeScan->new(-file => 'out.PrositeScan');

         Args    : -format => string representing the format type for the
                              ps_scan output, REQUIRED

       The "-format" argument must currently be set to "fasta" since this is the only parser
       implemented. This corresponds with using the ps_scan arguments "-o fasta".

         Returns : a Bio::SeqFeature::FeaturePair object where
                   feature1 is the matched subsequence and
                   feature2 is the PROSITE accession number.
