Bio::Index::EMBL - Interface for indexing (multiple) EMBL/Swissprot .dat files (ie flat file embl/swissprot format).
# Complete code for making an index for several # EMBL files use Bio::Index::EMBL; my $Index_File_Name = shift; my $inx = Bio::Index::EMBL->new($Index_File_Name, 'WRITE'); $inx->make_index(@ARGV); # Print out several sequences present in the index # in Fasta format use Bio::Index::EMBL; my $Index_File_Name = shift; my $inx = Bio::Index::EMBL->new($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 $seq1 = $inx->get_Seq_by_id($id); my $seq2 = $inx->get_Seq_by_acc($acc);
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's Fasta system.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : _initialize Usage : $index->_initialize Function: Calls $index->SUPER::_initialize(), and then adds the default id parser for EMBL files. Example : Returns : Args :
Title : _index_file 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. Example : Returns : Args :
Title : _file_format Usage : Internal function for indexing system Function: Provides file format for this database Example : Returns : Args :
