NAME

       Bio::Index::EMBL - Interface for indexing (multiple) EMBL/Swissprot .dat files (i.e. flat
       file EMBL/Swissprot format).

SYNOPSIS

           # Complete code for making an index for several
           # EMBL files
           use Bio::Index::EMBL;
           use strict;

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

           # Print out several sequences present in the index
           # in Fasta format
           use Bio::Index::EMBL;
           use strict;

           my $Index_File_Name = shift;
           my $inx = Bio::Index::EMBL->new(-filename => $Index_File_Name);
           my $out = Bio::SeqIO->new(-format => 'Fasta',-fh => \*STDOUT);

           foreach my $id (@ARGV) {
               my $seq = $inx->fetch($id); # Returns Bio::Seq object
               $out->write_seq($seq);
           }

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

DESCRIPTION

       Inherits functions for managing dbm files from Bio::Index::Abstract.pm, and provides the
       basic funtionallity for indexing EMBL files, and retrieving the sequence from them.
       Heavily snaffled from James Gilbert and his Fasta system. Note: for best results 'use
       strict'.

       The keys are the identifiers in the ID and AC lines.

       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.

         Usage   : $index->_index_file( $file_name, $i )
         Function: Specialist function to index EMBL format files.
                   Is provided with a filename and an integer
                   by make_index in its SUPER class.
