NAME¶
Bio::Search::Result::GenericResult - Generic Implementation of Bio::Search::Result::ResultI interface applicable to most search results.
SYNOPSIS¶
# typically one gets Results from a SearchIO stream use Bio::SearchIO; my $io = Bio::SearchIO->new(-format => 'blast', -file => 't/data/HUMBETGLOA.tblastx'); while( my $result = $io->next_result ) { # process all search results within the input stream while( my $hit = $result->next_hit ) { # insert code here for hit processing } } use Bio::Search::Result::GenericResult; my @hits = (); # would be a list of Bio::Search::Hit::HitI objects # typically these are created from a Bio::SearchIO stream my $result = Bio::Search::Result::GenericResult->new ( -query_name => 'HUMBETGLOA', -query_accession => '' -query_description => 'Human haplotype C4 beta-globin gene, complete cds.' -query_length => 3002 -database_name => 'ecoli.aa' -database_letters => 4662239, -database_entries => 400, -parameters => { 'e' => '0.001' }, -statistics => { 'kappa' => 0.731 }, -algorithm => 'blastp', -algorithm_version => '2.1.2', ); my $id = $result->query_name(); my $desc = $result->query_description(); my $name = $result->database_name(); my $size = $result->database_letters(); my $num_entries = $result->database_entries(); my $gap_ext = $result->get_parameter('e'); my @params = $result->available_parameters; my $kappa = $result->get_statistic('kappa'); my @statnames = $result->available_statistics;
# TODO: Show how to configure a SearchIO stream so that it generates # GenericResult objects.
DESCRIPTION¶
This object is an implementation of the Bio::Search::Result::ResultI interface and provides a generic place to store results from a sequence database search.
Unless you're writing a parser, you won't ever need to create a GenericResult or any other ResultI-implementing object. If you use the SearchIO system, ResultI objects are created automatically from a SearchIO stream which returns Bio::Search::Result::ResultI objects.
For documentation on what you can do with GenericResult (and other ResultI objects), please see the API documentation in Bio::Search::Result::ResultI.
FEEDBACK¶
Mailing Lists¶
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

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.
Reporting Bugs¶
