NAME

Bio::Search::Result::HmmpfamResult - A parser and result object for hmmpfam results

SYNOPSIS

    # generally we use Bio::SearchIO to build these objects
    use Bio::SearchIO;
    my $in = new Bio::SearchIO(-format => 'hmmer_pull',
							   -file   => 'result.hmmer');

    while (my $result = $in->next_result) {
		print $result->query_name, " ", $result->algorithm, " ", $result->num_hits(), " hits\n";
    }

DESCRIPTION

This object implements a parser for hmmpfam result 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 = new Bio::SearchIO::Result::hmmpfam();
 Function: Builds a new Bio::SearchIO::Result::hmmpfam object 
 Returns : Bio::SearchIO::Result::hmmpfam
 Args    : -chunk  => [Bio::Root::IO, $start, $end] (required if no -parent)
           -parent => Bio::PullParserI object (required if no -chunk)
           -parameters => hash ref of search parameters (key => value), optional
           -statistics => hash ref of search statistics (key => value), optional

		   where the array ref provided to -chunk contains an IO object
           for a filehandle to something representing the raw data of the
           result, and $start and $end define the tell() position within the
           filehandle that the result data starts and ends (optional; defaults
           to start and end of the entire thing described by the filehandle)

next_hit

Title   : next_hit
Usage   : while( $hit = $result->next_hit()) { ... }
Function: Returns the next available Hit object, representing potential
          matches between the query and various entities from the database.
Returns : a Bio::Search::Hit::HitI object or undef if there are no more.
Args    : none

next_model

Title   : next_model
Usage   : my $domain = $result->next_model
Function: Returns the next domain - this is an alias for next_hit()
Returns : L<Bio::Search::Hit::HitI> object
Args    : none

hits

Title   : hits
Usage   : my @hits = $result->hits
Function: Returns the HitI objects contained within this Result
Returns : Array of Bio::Search::Hit::HitI objects
Args    : none

See Also: Bio::Search::Hit::HitI

models

Title   : models
Usage   : my @domains = $result->models;
Function: Returns the list of HMM models seen - this is an alias for hits()
Returns : Array of L<Bio::Search::Hit::HitI> objects
Args    : none

sort_hits

 Title		: sort_hits
 Usage		: $result->sort_hits('<score')
 Function	: Sorts the hits so that they come out in the desired order when
              hits() or next_hit() is called.
 Returns	: n/a
 Args		: A coderef for the sort function. See the documentation on the Perl
              sort() function for guidelines on writing sort functions.
			  You will be sorting array references, not HitI objects. The
			  references contain name as element 0, description as element 1,
			  score as element 2, significance as element 3 and number of hsps
			  as element 4.
			  By default the sort order is ascending significance value (ie.
			  most significant hits first).
 Note		: To access the special variables $a and $b used by the Perl sort()
              function the user function must access
			  Bio::Search::Result::HmmpfamResult namespace. 
              For example, use : 
              $result->sort_hits(
				sub{$Bio::Search::Result::HmmpfamResult::a->[2]
				                         <=> 
					$Bio::Search::Result::HmmpfamResult::b->[2]});
              NOT $result->sort_hits($a->[2] <=> $b->[2]);

rewind

Title   : rewind
Usage   : $result->rewind;
Function: Allow one to reset the Hit iterator to the beginning, so that
          next_hit() will subsequently return the first hit and so on.
Returns : n/a
Args    : none
