NAME

Bio::Tools::Phylo::Molphy - parser for Molphy output

SYNOPSIS

   use Bio::Tools::Phylo::Molphy;
   my $parser = Bio::Tools::Phylo::Molphy->new(-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 = Bio::TreeIO->new(-format => "newick");
     $out->write_tree($trees[0]); # writing only the 1st tree
   }
 
 

DESCRIPTION

A parser for Molphy output (protml,dnaml)

FEEDBACK

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.

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.

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

new

  Title   : new
  Usage   : my $obj = Bio::Tools::Phylo::Molphy->new();
  Function: Builds a new Bio::Tools::Phylo::Molphy object 
  Returns : Bio::Tools::Phylo::Molphy
  Args    : -fh/-file => $val, # for initing input, see Bio::Root::IO
 
 

next_result

  Title   : next_result
  Usage   : my $r = $molphy->next_result
  Function: Get the next result set from parser data
  Returns : Bio::Tools::Phylo::Molphy::Result object
