VERSION
version 1.7.3
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 ) {

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 the web:
