NAME

Bio::Search::HSP::HmmpfamHSP - A parser and HSP object for hmmpfam hsps

SYNOPSIS

    # generally we use Bio::SearchIO to build these objects
    use Bio::SearchIO;
    my $in = Bio::SearchIO->new(-format => 'hmmer_pull',
                                                           -file   => 'result.hmmer');
    while (my $result = $in->next_result) {
                while (my $hit = $result->next_hit) {
                        print $hit->name, "\n";
                        print $hit->score, "\n";
                        print $hit->significance, "\n";
                        while (my $hsp = $hit->next_hsp) {
                                # process HSPI objects
                        }
                }
    }

DESCRIPTION

This object implements a parser for hmmpfam hsp output, a program in the HMMER package.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

new

 Title   : new
 Usage   : my $obj = Bio::Search::HSP::HmmpfamHSP->new();
 Function: Builds a new Bio::Search::HSP::HmmpfamHSP object.
 Returns : Bio::Search::HSP::HmmpfamHSP
 Args    : -chunk  => [Bio::Root::IO, $start, $end] (required if no -parent)
           -parent => Bio::PullParserI object (required if no -chunk)
           -hsp_data => array ref with [rank query_start query_end hit_start
                                                                                hit_end score evalue]
           where the array ref provided to -chunk contains an IO object
           for a filehandle to something representing the raw data of the
           hsp, and $start and $end define the tell() position within the
           filehandle that the hsp data starts and ends (optional; defaults
           to start and end of the entire thing described by the filehandle)

query

 Title   : query
 Usage   : my $query = $hsp->query
 Function: Returns a SeqFeature representing the query in the HSP
 Returns : L<Bio::SeqFeature::Similarity>
 Args    : none

hit

 Title   : hit
 Usage   : my $hit = $hsp->hit
 Function: Returns a SeqFeature representing the hit in the HSP
 Returns : L<Bio::SeqFeature::Similarity>
 Args    : [optional] new value to set

gaps

 Title    : gaps
 Usage    : my $gaps = $hsp->gaps( ['query'|'hit'|'total'] );
 Function : Get the number of gaps in the query, hit, or total alignment.
 Returns  : Integer, number of gaps or 0 if none
 Args     : 'query' = num conserved / length of query seq (without gaps)
            'hit'   = num conserved / length of hit seq (without gaps)
            'total' = num conserved / length of alignment (with gaps)
            default = 'total'

pvalue

 Title   : pvalue
 Usage   : my $pvalue = $hsp->pvalue();
 Function: Returns the P-value for this HSP
 Returns : undef (Hmmpfam reports do not have p-values)
 Args    : none
