   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.

   Reporting Bugs
       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)
        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
        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)
        Returns : value of search_space
        Args    : newvalue (optional)
