SYNOPSIS

use Bio::DB::GFF;
# Open the sequence database
my $db = Bio::DB::GFF->new( -adaptor => 'dbi:mysql',
-dsn => 'dbi:mysql:elegans42',
-aggregator => ['so_transcript'],
);

Sub methods: CDS exon five_prime_UTR three_prime_UTR transcription_start_site polyA_site 5'-UTR 3'-UTR
------------------------------------------------------------------------

DESCRIPTION

Bio::DB::GFF::Aggregator::so_transcript is identical to the processed_transcript aggregator, which was designed to be compatible with the Sequence Ontology canonical gene. It aggregates raw ``exon,'' ``CDS'', ``five_prime_UTR'', ``three_prime_UTR'', ``transcription_start_site'' and ``polyA_site'' features into ``mRNA'' features. The UTRs may also be named ``untranslated_region,'' ``five_prime_untranslated_region,'' ``three_prime_untranslated_region,'', ``5'-UTR,'' and other synonyms.

The processed_transcript aggregator is loaded by default, so this is only needed for backward compatibility.
