NAME ^

Bio::Tools::Run::Phylo::Molphy::ProtML - A wrapper for the Molphy pkg app ProtML

SYNOPSIS ^

  use Bio::AlignIO;
  use Bio::TreeIO;
  use Bio::Tools::Run::Phylo::Molphy::ProtML;

  my %args = ( 'models' => 'jtt',
               'search' => 'quick',
               'other'  => [ '-information', '-w'] );
  my $verbose = 0; # change to 1 if you want some debugging output
  my $protml = Bio::Tools::Run::Phylo::Molphy::ProtML->new(-verbose => $verbose,
                                                          -flags   => \%args);

  die("cannot find the protml executable") unless $protml->executable;

  # read in a previously built protein alignment
  my $in = Bio::AlignIO->new(-format => 'clustalw',
                            -file   => 't/data/cel-cbr-fam.aln');
  my $aln = $in->next_aln;
  $protml->alignment($aln);

  my ($rc,$results) = $protml->run();

  # This may be a bit of overkill, but it is possible we could
  # have a bunch of results and $results is a
  # Bio::Tools::Phylo::Molphy object

  my $r = $results->next_result;
  # $r is a Bio::Tools::Phylo::Molphy::Result object

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

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

  my $out = Bio::TreeIO->new(-file => ">saved_MLtrees.tre",
                            -format => "newick");
  $out->write_tree($tree[0]);
  $out = undef;

DESCRIPTION ^

This is a wrapper for the exe from the Molphy (MOLecular PHYlogenetics) package by Jun Adachi & Masami Hasegawa. The software can be downloaded from http://www.ism.ac.jp/ismlib/softother.e.html. Note that PHYLIP (Joe Felsenstein) also provides a version of protml which this module is currently NOT prepared to handle. Use the package available directly from MOLPHY authors if you want to use the module in its present implementation (extensions are welcomed!).

The main components are the protml and nucml executables which are used to build maximum likelihood (ML) phylogenetic trees based on either protein or nucleotide sequences.

Here are the valid input parameters, we have added a longhand version of the parameters to help you understand what each one does. Either the longhand or the original Molphy parameter will work.

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.

  bioperl-l@bioperl.org                  - General discussion
  http://bioperl.org/wiki/Mailing_lists  - About the mailing lists

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.

Reporting Bugs
