NAME

Bio::Tools::Phylo::Molphy::Result - container for data parsed from a ProtML run

SYNOPSIS

# do not use this object directly, you will get it back as part of a 
# Molphy parser
use Bio::Tools::Phylo::Molphy;
my $parser = new Bio::Tools::Phylo::Molphy(-file => 'output.protml');
while( my $r = $parser->next_result ) {
  # r is a Bio::Tools::Phylo::Molphy::Result object

  # print the model name
  print $r->model, "\n";

  # get the substitution matrix
  # this is a hash of 3letter aa codes -> 3letter aa codes representing
  # substitution rate
  my $smat = $r->substitution_matrix;
  print "Arg -> Gln substitution rate is %d\n", 
        $smat->{'Arg'}->{'Gln'}, "\n";

  # get the transition probablity matrix
  # this is a hash of 3letter aa codes -> 3letter aa codes representing
  # transition probabilty
  my $tmat = $r->transition_probability_matrix;
  print "Arg -> Gln transition probablity is %.2f\n", 
        $tmat->{'Arg'}->{'Gln'}, "\n";

  # get the frequency for each of the residues
  my $rfreqs = $r->residue_frequencies;

  foreach my $residue ( keys %{$rfreqs} ) {
     printf "residue %s  expected freq: %.2f observed freq: %.2f\n",
            $residue,$rfreqs->{$residue}->[0], $rfreqs->{$residue}->[1];
  }

  my @trees;
  while( my $t = $r->next_tree ) {
      push @trees, $t;
  }

  print "search space is ", $r->search_space, "\n",
        "1st tree score is ", $trees[0]->score, "\n";

  # writing to STDOUT, use -file => '>filename' to specify a file
  my $out = new Bio::TreeIO(-format => "newick");
  $out->write_tree($trees[0]); # writing only the 1st tree
}

DESCRIPTION

APPENDIX

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

new

Title   : new
Usage   : my $obj = new Bio::Tools::Phylo::Molphy::Result();
Function: Builds a new Bio::Tools::Phylo::Molphy::Result object 
Returns : Bio::Tools::Phylo::Molphy::Result
Args    :

model

Title   : model
Usage   : $obj->model($newval)
Function: 
Returns : value of model
Args    : newvalue (optional)

substitution_matrix

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

transition_probability_matrix

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'

residue_frequencies

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

next_tree

Title   : next_tree
Usage   : my $tree = $factory->next_tree;
Function: Get the next tree from the factory
Returns : L<Bio::Tree::TreeI>
Args    : none

rewind_tree

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

add_tree

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>

search_space

Title   : search_space
Usage   : $obj->search_space($newval)
Function: 
Returns : value of search_space
Args    : newvalue (optional)
