Bio::Index::EMBL.3pm

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.
