NAME

Bio::SeqIO::embl - EMBL sequence input/output stream

SYNOPSIS

It is probably best not to use this object directly, but rather go through the AnnSeqIO handler system. Go:

    $stream = Bio::SeqIO->new(-file => $filename, -format => 'EMBL');

    while ( (my $seq = $stream->next_seq()) ) {
	# do something with $seq
    }

DESCRIPTION

This object can transform Bio::Seq objects to and from EMBL flat file databases.

There is alot of flexibility here about how to dump things which I need to document fully.

There should be a common object that this and genbank share (probably with swissprot). Too much of the magic is identical.

Optional functions

_show_dna()

(output only) shows the dna or not

_post_sort

(output only) provides a sorting func which is applied to the FTHelpers before printing

_id_generation_func

This is function which is called as

print "ID   ", $func($annseq), "\n";

To generate the ID line. If it is not there, it generates a sensible ID line using a number of tools.
