  use Bio::Tools::Phylo::PAML;
  my $parser = Bio::Tools::Phylo::PAML->new
    (-file => "./results/mlc", -dir => "./results/");

  # get the first/next result; a Bio::Tools::Phylo::PAML::Result object,
  # which isa Bio::SeqAnalysisResultI object.
  my $result = $parser->next_result();

  # Bio::PrimarySeq ancestral state reconstructions of the sequences

  # if you want to print the changes on the tree
  # this will print out the 
  # anc_aa       => ANCESTRAL AMINO ACID
  # anc_prob     => ANCESTRAL AA PROBABILITY 
  # derived_aa   => DERIVED AA

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.
