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.

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::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)
