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, "
";

	   # 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
",
		 $smat->{'Arg'}->{'Gln'}, "
";

	   # 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
",
		 $tmat->{'Arg'}->{'Gln'}, "
";

	   # 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
",
		     $residue,$rfreqs->{$residue}->[0], $rfreqs->{$residue}->[1];
	   }

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

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

	   # 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
	 }

       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.

	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
	Args	: none
