Bio::TreeIO::pag - Bio::TreeIO driver for Pagel format


  use Bio::TreeIO;
  my $in = Bio::TreeIO->new(-format => 'nexus',
                            -file   => 't/data/');

  my $out = Bio::TreeIO->new(-format => 'pag');
  while( my $tree = $in->next_tree ) {


Convert a Bio::TreeIO to Pagel format. More information here


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.                  - General discussion  - About the mailing lists


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.

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


 Title   : new
 Usage   : my $obj = Bio::TreeIO::pag->new();
 Function: Builds a new Bio::TreeIO::pag object 
 Returns : an instance of Bio::TreeIO::pag
 Args    : -file/-fh for filename or filehandles
           -name_length for minimum name length (default = 10)


 Title   : write_tree
 Usage   :
 Function: Write a tree out in Pagel format
           Some options are only appropriate for bayesianmultistate and
           the simpler output is only proper for discrete
 Returns : none
 Args    : -no_outgroups => (number)
           -print_header => 0/1 (leave 0 for discrete, 1 for bayesianms)
           -special_node => special node - not sure what they wanted to do here
           -keep_outgroup => 0/1 (keep the outgroup node in the output)
           -outgroup_ancestor => Bio::Tree::Node (if we want to exclude or include the outgroup this is what we operate on)
           -tree_no       => a tree number label - only useful for BayesianMultistate


 Title   : next_tree
 Usage   :
 Example :
 Returns : 
 Args    :


 Title   : name_length
 Usage   : $self->name_length(20);
 Function: set minimum taxon name length
 Returns : integer (length of name)
 Args    : integer
