NAME ^

Bio::Taxonomy::Tree - An Organism Level Implementation of TreeI interface.

SYNOPSIS ^

    # NB: This module is deprecated. Use Bio::Taxon in combination with
    # Bio::Tree::Tree instead

    # like from a TreeIO
    my $treeio = Bio::TreeIO->new(-format => 'newick', -file => 'treefile.dnd');
    my $tree = $treeio->next_tree;
    my @nodes = $tree->get_nodes;
    my $root = $tree->get_root_node;
    my @leaves = $tree->get_leaves;

DESCRIPTION ^

This object holds handles to Taxonomic Nodes which make up a tree.

EXAMPLES ^

  use Bio::Species;
  use Bio::Taxonomy::Tree;

  my $human=Bio::Species->new();
  my $chimp=Bio::Species->new();
  my $bonobo=Bio::Species->new();

  $human->classification(qw( sapiens Homo Hominidae
                             Catarrhini Primates Eutheria
                             Mammalia Euteleostomi Vertebrata 
                             Craniata Chordata
                             Metazoa Eukaryota ));

               'no rank 1','no rank 2','class','no rank 3','order',
               'suborder','family','genus','species');
