NAME

       Bio::Tools::Run::Phylo::Phylip::Consense - Wrapper for the phylip program Consense

SYNOPSIS

         use Bio::Tools::Run::Phylo::Phylip::Consense;
         use Bio::Tools::Run::Phylo::Phylip::SeqBoot;
         use Bio::Tools::Run::Phylo::Phylip::ProtDist;
         use Bio::Tools::Run::Phylo::Phylip::Neighbor;
         use Bio::Tools::Run::Phylo::Phylip::DrawTree;

         #first get an alignment
         my $aio= Bio::AlignIO->new(-file=>$ARGV[0],-format=>"clustalw");
         my $aln = $aio->next_aln;

         # To prevent truncation of sequence names by PHYLIP runs, use set_displayname_safe
         my ($aln_safe, $ref_name)=$aln->set_displayname_safe();

         #next use seqboot to generate multiple aligments
         my @params = ('datatype'=>'SEQUENCE','replicates'=>10);
         my $seqboot_factory = Bio::Tools::Run::Phylo::Phylip::SeqBoot->new(@params);

         my $aln_ref= $seqboot_factory->run($aln);

         Or, for long sequence names:

         my $aln_ref= $seqboot_factory->run($aln_safe);

         #next build distance matrices and construct trees
         my $pd_factory = Bio::Tools::Run::Phylo::Phylip::ProtDist->new();

           push @tree, $ne_factory->create_tree($mat);
         }

         #now use consense to get a final tree
         my $con_factory = Bio::Tools::Run::Phylo::Phylip::Consense->new();

         #you may set outgroup either by the number representing the order in
         #which species are entered or by the name of the species

         $con_factory->outgroup(1);
         $con_factory->outgroup('HUMAN');

         my $tree = $con_factory->run(\@tree);

         # Restore original sequence names, after ALL phylip runs:
         my @nodes = $tree->get_nodes();
         foreach my $nd (@nodes){
            $nd->id($ref_name->{$nd->id_output}) if $nd->is_Leaf;
         }

         #now draw the tree
         my $draw_factory = Bio::Tools::Run::Phylo::Phylip::DrawTree->new();
         my $image_filename = $draw_factory->draw_tree($tree);

DESCRIPTION

       Wrapper for phylip consense program

       Taken from phylip documentation...

       CONSENSE reads a file of computer-readable trees and prints out (and may also write out
       onto a file) a consensus tree. At the moment it carries out a family of consensus tree
       methods called the M[l] methods (Margush and McMorris, 1981). These include strict
       consensus and majority rule consensus. Basically the consensus tree consists of
       monophyletic groups that occur as often as possible in the data.

       More documentation on using Consense and setting parameters may be found in the phylip
       package.

       VERSION Support

       This wrapper currently supports v3.5 of phylip. There is also support for v3.6 although
       this is still experimental as v3.6 is still under alpha release and not all
       functionalities maybe supported.

PARAMETERS FOR Consense

   TYPE
       Title          : TYPE Description    : (optional)
                    Only available in phylip v3.6

                         This program supports 3 types of consensus generation

                         MRe   : Majority Rule (extended) Any set of species that
                                 appears in more than 50% of the trees is included.
                                 The program then considers the other sets of species
                                 in order of the frequency with which they have appeared,
                                 adding to the consensus tree any which are compatible
                                 with it until

                         STRICT: A set of species must appear in all input trees to be
                                 included in the strict consensus tree.

                         MR    :  A set of species is included in the consensus tree
                                 if it is present in more than half of the input trees.

                         Ml    : The user is asked for a fraction between 0.5 and 1, and
                                 the program then includes in the consensus tree any set
                                 of species that occurs among the input trees more than
                                 that fraction of then time. The Strict consensus and the
                                 Majority Rule consensus are extreme cases of the M[l] consensus,
                                 being for fractions of 1 and 0.5 respectively

                         usage: my $factory = Bio::Tools::Run::Phylo::Phylip::Consense->new(-type=>"Ml 0.7");

                    Defaults to MRe

   ROOTED
         Title: ROOTED
         Description: (optional)

                    toggles between the default assumption that the input trees are unrooted trees and
                    the selection that specifies that the tree is to be treated as a rooted tree and not
                    re-rooted. Otherwise the tree will be treated as outgroup-rooted and will be
                    re-rooted automatically at the first species encountered on the first tree
                    (or at a species designated by the Outgroup option)

                    usage: my $factory = Bio::Tools::Run::Phylo::Phylip::Consense->new(-rooted=>1);

                    Defaults to unrooted

   OUTGROUP
         Title         : OUTGROUP
         Description   : (optional)

                       It is in effect only if the Rooted option selection is not in effect.
                       The trees will be re-rooted with a species of your choosing.

                       usage  my $factory = Bio::Tools::Run::Phylo::Phylip::Consense->new(-outgroup=>2);

                       Defaults to first species encountered.

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 one of the Bioperl mailing lists.  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.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their
       resolution.  Bug reports can be submitted via the web:
