Bio::SeqIO::game(3) a class for parsing and writing game-XML


This module is not used directly, use SeqIO.

use Bio::SeqIO;
my $in = Bio::SeqIO->new ( -file => 'file.xml',
-format => 'game',
-verbose => 1 );
my $seq = $in->next_seq;


Bio::SeqIO::game will parse game XML (version 1.2) or write game XML from a Bio::SeqI implementing object. The XML is readable by the genome annotation editor 'Apollo' ( It is not backwards compatible with the previous version of game XML. The XML format currently used by Apollo contains a single 'main' annotated sequence, so we will only get a single annotated sequence in the stream when parsing a game-XML record.
