NAME

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

CONTENTS

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.
