NAME

       Bio::DB::Taxonomy::greengenes - Use the Greengenes taxonomy

SYNOPSIS

         use Bio::DB::Taxonomy;

         my $db = Bio::DB::Taxonomy->new(
            -source   => 'greengenes',
            -taxofile => 'taxonomy_16S_candiv_gg_2011_1.txt'
         );

DESCRIPTION

       This module is in beta. Its interface or its results may change in a future update.

       Bio::DB::Taxonomy::greengenes is an implementation of Bio::DB::Taxonomy which stores and
       accesses the Greengenes taxonomy of Bacteria and Archaea. Internally, it keeps the
       taxonomy into memory by using Bio::DB::Taxonomy::list. As a consequence, note that the IDs
       assigned to the taxonomy nodes, e.g. gg123, are arbitrary, contrary to the pre-defined IDs
       that NCBI assigns to taxons.

       The latest release of the Greengene taxonomy (2011) contains about 4,600 taxa and occupies
       about 4MB of memory once parsed into a Bio::DB::Taxonomy::greengenes object. The taxonomy
       files taxonomy_16S_all_gg_2011_1.txt and taxonomy_16S_candiv_gg_2011_1.txt that this
       module can use are available from
       <http://www.secondgenome.com/go/2011-greengenes-taxonomy/>.

   Support
       Please direct usage questions or support issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.
