NAME

Bio::Tools::Phylo::PAML::ModelResult - A container for NSSite Model Result from PAML

CONTENTS

SYNOPSIS



  # get a ModelResult from a PAML::Result object
  use Bio::Tools::Phylo::PAML;
  my $paml = Bio::Tools::Phylo::PAML->new(-file => mlc);
  my $result = $paml->next_result;
  foreach my $model ( $result->get_NSSite_results ) {
    print $model->model_num, " ", $model->model_description, "\n";
    print $model->kappa, "\n";
    print $model->run_time, "\n";
# if you are using PAML < 3.15 then only one place for POS sites
   for my $sites ( $model->get_pos_selected_sites ) {
    print join("\t",@$sites),"\n";
   }
# otherwise query NEB and BEB slots
   for my $sites ( $model->get_NEB_pos_selected_sites ) {
     print join("\t",@$sites),"\n";
   }

   for my $sites ( $model->get_BEB_pos_selected_sites ) {

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.

    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 of the bugs and their resolution. Bug reports can be submitted via email or the web:
