NAME

Bio::TreeIO - Parser for Tree files

SYNOPSIS

            

              
              
{
    use Bio::TreeIO;
    my $treeio = Bio::TreeIO->new(-format => 'newick',
                                  -file   => 'globin.dnd');
    while( my $tree = $treeio->next_tree ) {
print "Tree is ", $tree->number_nodes, "\n";
    }
}
            
          

DESCRIPTION

This is the driver module for Tree reading from data streams and flatfiles. This is intended to be able to create Bio::Tree::TreeI objects.
