NAME

Bio::Tools::Run::Phylo::Njtree::Best - Wrapper around the Njtree (Njtree/phyml) best program.

CONTENTS

SYNOPSIS



  use Bio::Tools::Run::Phylo::Njtree::Best;
  use Bio::AlignIO;
  use Bio::TreeIO;

  my $alignio = Bio::AlignIO->new(-format => fasta,
                                 -file   => t/data/njtree_aln2.nucl.mfa);

  my $aln = $alignio->next_aln;

  my $treeio = Bio::TreeIO->new(
      -format => nhx, -file => t/data/species_tree_njtree.nh);

  my $tree = $treeio->next_tree;

  my $njtree_best = Bio::Tools::Run::Phylo::Njtree::Best->new();
  $njtree_best->alignment($aln);
  $njtree_best->tree($tree);
  my $nhx_tree = $njtree_best->run();



DESCRIPTION

This is a wrapper around the best program of Njtree by Li Heng. See http://treesoft.sourceforge.net/njtree.shtml for more information.

Wrapper for the calculation of a reconciled phylogenetic tree with inferred duplication tags from amultiple sequence alignment and a species tree using NJTREE.

    Helping the module find your executable

You will need to enable NJTREEDIR to find the njtree program. This can be done in (at least) three ways:



  1. Make sure the njtree executable is in your path (i.e.
     which njtree returns a valid program
  2. define an environmental variable NJTREEDIR which points to a
     directory containing the njtree app:
   In bash
        export NJTREEDIR=/home/progs/treesoft/njtree   or
   In csh/tcsh
        setenv NJTREEDIR /home/progs/treesoft/njtree

  3. include a definition of an environmental variable NJTREEDIR
      in every script that will
     BEGIN {$ENV{NJTREEDIR} = /home/progs/treesoft/njtree; }
     use Bio::Tools::Run::Phylo::Njtree::Best;



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:
