NAME

Bio::SeqIO::swiss - Swissprot sequence input/output stream

SYNOPSIS

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

use Bio::SeqIO;

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

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

DESCRIPTION

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

There is a lot of flexibility here about how to dump things which needs to be documented.

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   ", $func($seq), "\n";

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

If you want to output annotations in Swissprot format they need to be stored in a Bio::Annotation::Collection object which is accessible through the Bio::SeqI interface method annotation().

The following are the names of the keys which are polled from a Bio::Annotation::Collection object.

reference   - Should contain Bio::Annotation::Reference objects
comment     - Should contain Bio::Annotation::Comment objects
dblink      - Should contain Bio::Annotation::DBLink objects
gene_name   - Should contain Bio::Annotation::SimpleValue object
