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

 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
 Args    : none
