Bio::Index::GenBank(3)User Contributed Perl DocumentatioBio::Index::GenBank(3)

       Bio::Index::GenBank - Interface for indexing one	or more	GenBank	files
       (i.e. flat file GenBank format).

	   # Complete code for making an index for one or more GenBank files
	   use strict;
	   use Bio::Index::GenBank;

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

	   # Print out sequences present in the	index in gcg format
	   use Bio::Index::GenBank;
	   use Bio::SeqIO;
	   use strict;

	   my $Index_File_Name = shift;
	   my $inx = Bio::Index::GenBank->new(-filename	=> $Index_File_Name);
	   my $seqio = Bio::SeqIO->new(-format => 'gcg');
	   foreach my $id (@ARGV) {
	       my $seq = $inx->fetch($id); # Returns Bio::Seq object

	   # alternatively
	   my ($locus, $acc);
	   my $seq1 = $inx->get_Seq_by_id($locus);
	   my $seq2 = $inx->get_Seq_by_acc($acc);

       By default the index that is created uses the LOCUS, ACCESSION, and
       VERSION identifiers as keys. Inherits functions for managing dbm	files
       from, and provides the basic functionality for
       indexing	GenBank	files, and retrieving the sequence from	them. For best
       results 'use strict'.

       You can also set	or customize the unique	key used to retrieve by
       writing your own	function and calling the id_parser() method.  For

	  # make the index

	  # here is where the retrieval	key is specified
	  sub get_id {
	     my	$line =	shift;
	     $line =~ /clone="(\S+)"/;

   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.
