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.

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.
Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution. Bug reports can be submitted via the web:

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : new Usage : my $obj = Bio::Tools::Phylo::Molphy::Result->new(); Function: Builds a new Bio::Tools::Phylo::Molphy::Result object Returns : Bio::Tools::Phylo::Molphy::Result Args :
Title : model Usage : $obj->model($newval) Function: Returns : value of model Args : newvalue (optional)
Title : substitution_matrix
Usage : my $smat = $result->subsitution_matrix;
Function: Get the relative substitution matrix calculated in the ML procedure
Returns : reference to hash of hashes where key is the aa/nt name and value
is another hash ref which contains keys for all the aa/nt
possibilities
Args : none
Title : transition_probability_matrix
Usage : my $matrixref = $molphy->transition_probablity_matrix();
Function: Gets the observed transition probability matrix
Returns : hash of hashes of aa/nt transition to each other aa/nt
Args : Transition matrix type, typically
'1PAM-1.0e05' or '1PAM-1.0e07'
Title : residue_frequencies
Usage : my %data = $molphy->residue_frequencies()
Function: Get the modeled and expected frequencies for
each of the residues in the sequence
Returns : hash of either aa (protml) or nt (nucml) frequencies
each key will point to an array reference where
1st slot is model's expected frequency
2nd slot is observed frequency in the data
$hash{'A'}->[0] =
Args : none
Title : next_tree Usage : my $tree = $factory->next_tree; Function: Get the next tree from the factory Returns : L<Bio::Tree::TreeI> Args : none
Title : rewind_tree_iterator
Usage : $result->rewind_tree()
Function: Rewinds the tree iterator so that next_tree can be
called again from the beginning
Returns : none
Args : none
Title : add_tree Usage : $result->add_tree($tree); Function: Adds a tree Returns : integer which is the number of trees stored Args : L<Bio::Tree::TreeI>
Title : search_space Usage : $obj->search_space($newval) Function: Returns : value of search_space Args : newvalue (optional)
