NAME

       Bio::DB::Taxonomy::silva - Use the Silva taxonomy

SYNOPSIS

         use Bio::DB::Taxonomy;

         my $db = Bio::DB::Taxonomy->new(
            -source   => 'silva',
            -taxofile => 'SSURef_108_tax_silva_trunc.fasta',
         );

DESCRIPTION

       This is an implementation of Bio::DB::Taxonomy which stores and accesses the Silva
       taxonomy. Internally, Bio::DB::Taxonomy::silva 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. sv72, are arbitrary, contrary to the pre-defined IDs that NCBI assigns to
       taxons. Note also that no rank names or common names are assigned to the taxa of
       Bio::DB::Taxonomy::silva.

       The latest Silva taxonomy (2011) contains about 126,000 taxa and occupies about 124 MB of
       memory once parsed into a Bio::DB::Taxonomy::silva object.  Obviously, it can take a
       little while to load.

       The taxonomy file SSURef_108_tax_silva_trunc.fasta that this module uses is available from
       <http://www.arb-silva.de/no_cache/download/archive/release_108/Exports/>.

   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to the Bioperl mailing list.  Your participation
       is much appreciated.

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

       bioperl-l@bioperl.org

       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.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their
