NAME

       Bio::DB::GFF::Aggregator::transcript -- Transcript aggregator

SYNOPSIS

         use Bio::DB::GFF;

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

        -------------------------------------------------
        Aggregator method: transcript

DESCRIPTION

       Bio::DB::GFF::Aggregator::transcript is one of the default aggregators, and was written to
       be compatible with the C elegans GFF files.  It aggregates raw ""exon", "CDS", "5'UTR",
       "3'UTR", "polyA" and "TSS" features into "transcript" features.  For compatibility with
       the idiosyncrasies of the Sanger GFF format, it expects that the full range of the
       transcript is contained in a main feature of type "Transcript" (notice the capital "T").

       Internally this module is very simple.  To override it with one that recognizes a main
       feature named "gene", simply follow this template:

        my $db = Bio::DB::GFF->new(...etc...)
        my $aggregator = Bio::DB::GFF::Aggregator->new(-method => 'transcript',
                                                       -main_method => 'gene',
                                                       -sub_parts => ['exon','CDS']);
        $db->add_aggregator($aggregator);

   main_name
        Title   : main_name
        Usage   : $aggregator->main_name
        Function: return the method for the main component
