NAME

Bio::Search::Hit::HmmpfamHit - A parser and hit object for hmmpfam hits

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) {
		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 hit 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::Search::Hit::HmmpfamHit();
 Function: Builds a new Bio::Search::Hit::HmmpfamHit object.
 Returns : Bio::Search::Hit::HmmpfamHit
 Args    : -chunk    => [Bio::Root::IO, $start, $end] (required if no -parent)
           -parent   => Bio::PullParserI object (required if no -chunk)
           -hit_data => array ref with [name description score significance
		                                num_hsps rank]

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

next_hsp

Title    : next_hsp
Usage    : while( $hsp = $obj->next_hsp()) { ... }
Function : Returns the next available High Scoring Pair
Example  : 
Returns  : L<Bio::Search::HSP::HSPI> object or null if finished
Args     : none

next_domain

Title   : next_domain 
Usage   : my $domain = $hit->next_domain();
Function: An alias for L<next_hsp()>, this will return the next HSP
Returns : L<Bio::Search::HSP::HSPI> object
Args    : none

hsps

Usage     : $hit_object->hsps();
Purpose   : Get a list containing all HSP objects.
Example   : @hsps = $hit_object->hsps();
Returns   : list of L<Bio::Search::HSP::BlastHSP> objects.
Argument  : none

domains

Title   : domains
Usage   : my @domains = $hit->domains();
Function: An alias for L<hsps()>, this will return the full list of hsps
Returns : array of L<Bio::Search::HSP::HSPI> objects
Args    : none

hsp

Usage     : $hit_object->hsp( [string] );
Purpose   : Get a single HSPI object for the present HitI object.
Example   : $hspObj  = $hit_object->hsp;  # same as 'best'
          : $hspObj  = $hit_object->hsp('best');
          : $hspObj  = $hit_object->hsp('worst');
Returns   : Object reference for a L<Bio::Search::HSP::HSPI> object.
Argument  : String (or no argument).
          :   No argument (default) = highest scoring HSP (same as 'best').
          :   'best'  = highest scoring HSP.
          :   'worst' = lowest scoring HSP.
Throws    : Exception if an unrecognized argument is used.

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

strand

 Usage     : $sbjct->strand( [seq_type] );
 Purpose   : Gets the strand(s) for the query, sbjct, or both sequences.
           : For hmmpfam, the answers are always 1 (forward strand).
 Example   : $qstrand = $sbjct->strand('query');
           : $sstrand = $sbjct->strand('hit');
           : ($qstrand, $sstrand) = $sbjct->strand();
 Returns   : scalar context: integer '1'
           : array context without args: list of two strings (1, 1)
           : Array context can be "induced" by providing an argument of 'list'
		   : or 'array'.
 Argument  : In scalar context: seq_type = 'query' or 'hit' or 'sbjct' (default
           : = 'query') ('sbjct' is synonymous with 'hit')

frac_aligned_query

Usage     : $hit_object->frac_aligned_query();
Purpose   : Get the fraction of the query sequence which has been aligned
          : across all HSPs (not including intervals between non-overlapping
          : HSPs).
Example   : $frac_alnq = $hit_object->frac_aligned_query();
Returns   : undef (the length of query sequences is unknown in Hmmpfam reports)
Argument  : none
