NAME

Bio::Search::Result::HMMERResult - A Result object for HMMER results

SYNOPSIS

    use Bio::Search::Result::HMMERResult;
    my $result = Bio::Search::Result::HMMERResult->new
    ( -hmm_name => 'pfam',
      -sequence_file => 'roa1.pep',
      -hits => \@hits);

    # generally we use Bio::SearchIO to build these objects
    use Bio::SearchIO;
    my $in = Bio::SearchIO->new(-format => 'hmmer',
			       -file   => 'result.hmmer');
    while( my $result = $in->next_result ) {
	print $result->query_name, " ", $result->algorithm, " ", $result->num_hits(), " hits\n";
    }

DESCRIPTION

This is a specialization of Bio::Search::Result::GenericResult. There are a few extra methods, specifically sequence_file, hmm_name, next_models, and models.

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.
