Bio::Index::SwissPfam - Interface for indexing swisspfam files


    use Bio::Index::SwissPfam;
    use strict;

    my $Index_File_Name = shift;
    my $inx = Bio::Index::SwissPfam->new('-filename' => $Index_File_Name, 
                                         '-write_flag' => 'WRITE');

    use Bio::Index::SwissPfam;
    use strict;

    my $Index_File_Name = shift;
    my $inx = Bio::Index::SwissPfam->new('-filename' => $Index_File_Name);

    foreach my $id (@ARGV) {
        my $seq = $inx->fetch($id); # Returns stream
             while( <$seq> ) {
                 if(/^>/) {


SwissPfam is one of the flat files released with Pfam. This modules provides a way of indexing this module.

Inherits functions for managing dbm files from, and provides the basic funtionality for indexing SwissPfam files. Only retrieves FileStreams at the moment. Once we have something better (ie, an object!), will use that. Heavily snaffled from Index::Fasta system of James Gilbert. Note: for best results 'use strict'.


Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.                  - General discussion  - About the mailing lists


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

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.
