NAME ^

Bio::Tools::Run::Simprot - Wrapper around the Simprot program. Wrapper for the calculation of a multiple sequence alignment from a phylogenetic tree

SYNOPSIS ^

  use Bio::Tools::Run::Simprot;
  use Bio::TreeIO;

  my $treeio = Bio::TreeIO->new(
      -format => 'nh', -file => 't/data/tree.nh');

  my $tree = $treeio->next_tree;

  my $simprot = Bio::Tools::Run::Simprot->new();
  $simprot->tree($tree);
  my ($rc,$aln,$seq) = $simprot->run();

DESCRIPTION ^

This is a wrapper around the Simprot program by Andy Pang, Andrew D Smith, Paulo AS Nuin and Elisabeth RM Tillier.

Simprot allows for several models of amino acid substitution (PAM, JTT and PMB), allows for gamma distributed sites rates according to Yang's model, and implements a parameterised Qian and Goldstein distribution model for insertion and deletion.

See http://www.uhnres.utoronto.ca/labs/tillier/software.htm for more information.

Helping the module find your executable

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

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

  3. include a definition of an environmental variable SIMPROTDIR 
      in every script that will
     BEGIN {$ENV{SIMPROTDIR} = '/home/progs/simprot'; }
     use Bio::Tools::Run::Simprot;

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.
