NAME ^

Bio::Search::Result::BlastPullResult - A parser and result object for BLASTN results

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) {
                print $result->query_name, " ", $result->algorithm, " ", $result->num_hits(), " hits\n";
    }

DESCRIPTION ^

This object implements a parser for NCBI BLASTN result output.

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::SearchIO::Result::hmmpfam->new();
 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

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

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.
                          By default the sort order is ascending significance value (ie.
                          most significant hits first).
                          *** example

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

get_statistic

 Title   : get_statistic
 Usage   : my $gap_ext = $result->get_statistic('kappa')
 Function: Returns the value for a specific statistic available 
           from this result
 Returns : string
 Args    : name of statistic (string)

get_parameter

 Title   : get_parameter
 Usage   : my $gap_ext = $result->get_parameter('gapext')
 Function: Returns the value for a specific parameter used
           when running this result
 Returns : string
 Args    : name of parameter (string)
