SYNOPSIS

use Bio::DB::GFF;
# Open the sequence database
my $db = Bio::DB::GFF->new( -adaptor => 'dbi:mysql',
-dsn => 'dbi:mysql:elegans42',
-aggregator => ['coding'],
);
------------------------------------------------------------------------
Aggregator method: coding
Main method: mRNA
Sub methods: CDS
------------------------------------------------------------------------

DESCRIPTION

Bio::DB::GFF::Aggregator::coding aggregates ``CDS'' features into a feature called ``coding'' and was written to be compatible with the Sequence Ontology canonical gene. The CDS features are expected to belong to a parent of type ``mRNA,'' but the aggregator will work even if this isn't the case.
