NAME

Bio::Search::Hit::BlastPullHit - A parser and hit object for BLASTN hits

CONTENTS

SYNOPSIS



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

    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 BLASTN hit output.

    Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

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::Hit::BlastNHit->new();
 Function: Builds a new Bio::Search::Hit::BlastNHit object.
 Returns : Bio::Search::Hit::BlastNHit
 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]

           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



    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



    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 HSP iterator to the beginning, so that
           next_hsp() will subsequently return the first hsp and so on.
 Returns : n/a
 Args    : none
