NAME

Bio::DB::Taxonomy::flatfile - Use the NCBI taxonomy from local indexed flat files

CONTENTS

SYNOPSIS



  use Bio::DB::Taxonomy;

  my $db = Bio::DB::Taxonomy->new(-source    => flatfile ,
                                  -nodesfile => nodes.dmp,
                                  -namesfile => names.dmp);



DESCRIPTION

This is an implementation of Bio::DB::Taxonomy which stores and accesses the NCBI taxonomy using flat files stored locally on disk and indexed using the DB_File module RECNO data structure for fast retrieval.

The required database files, nodes.dmp and names.dmp can be obtained from ftp://ftp.ncbi.nih.gov/pub/taxonomy/taxdump.tar.gz

FEEDBACK

    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.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

    new



 Title   : new
 Usage   : my $obj = Bio::DB::Taxonomy::flatfile->new();
 Function: Builds a new Bio::DB::Taxonomy::flatfile object
 Returns : an instance of Bio::DB::Taxonomy::flatfile
 Args    : -directory => name of directory where index files should be created
           -nodesfile => name of file containing nodes (nodes.dmp from NCBI)
           -namesfile => name of the file containing names(names.dmp from NCBI)
           -force     => 1 to replace current indexes even if they exist



    Bio::DB::Taxonomy interface implementation

    get_num_taxa



 Title   : get_num_taxa
 Usage   : my $num = $db->get_num_taxa();
 Function: Get the number of taxa stored in the database.
 Returns : A number
 Args    : None



    get_taxon



 Title   : get_taxon
 Usage   : my $taxon = $db->get_taxon(-taxonid => $taxonid)
 Function: Get a Bio::Taxon object from the database.
 Returns : Bio::Taxon object
 Args    : just a single value which is the database id, OR named args:
           -taxonid => taxonomy id (to query by taxonid)
            OR
           -name    => string (to query by a taxonomy name: common name,
                               scientific name, etc)



    get_taxonids



 Title   : get_taxonids
 Usage   : my @taxonids = $db->get_taxonids(Homo sapiens);
 Function: Searches for a taxonid (typically ncbi_taxon_id) based on a query
           string. Note that multiple taxonids can match to the same supplied
           name.
 Returns : array of integer ids in list context, one of these in scalar context
 Args    : string representing taxons name



    get_Children_Taxids



 Title   : get_Children_Taxids
 Usage   : my @childrenids = $db->get_Children_Taxids
 Function: Get the ids of the children of a node in the taxonomy
 Returns : Array of Ids
 Args    : Bio::Taxon or a taxon_id
 Status  : deprecated (use each_Descendent())



    ancestor



 Title   : ancestor
 Usage   : my $ancestor_taxon = $db->ancestor($taxon)
 Function: Retrieve the full ancestor taxon of a supplied Taxon from the
           database.
 Returns : Bio::Taxon
 Args    : Bio::Taxon (that was retrieved from this database)



    each_Descendent



 Title   : each_Descendent
 Usage   : my @taxa = $db->each_Descendent($taxon);
 Function: Get all the descendents of the supplied Taxon (but not their
           descendents, ie. not a recursive fetchall).
 Returns : Array of Bio::Taxon objects
 Args    : Bio::Taxon (that was retrieved from this database)



    Helper methods

    index_directory



 Title   : index_directory
 Funtion : Get/set the location that index files are stored. (this module
           will index the supplied database)
 Usage   : $obj->index_directory($newval)
 Returns : value of index_directory (a scalar)
 Args    : on set, new value (a scalar or undef, optional)
