Title : new
Usage : my $obj = Bio::Tools::Phylo::PAML::ModelResult->new();
Function: Builds a new Bio::Tools::Phylo::PAML::ModelResult object
Returns : an instance of Bio::Tools::Phylo::PAML::ModelResult
Args : -model_num => model number
-model_description => model description
-kappa => value of kappa
-time_used => amount of time
-pos_sites => arrayref of sites under positive selection
-neb_sites => arrayref of sites under positive selection (by NEB analysis)
-beb_sites => arrayref of sites under positive selection (by BEB analysis)
-trees => arrayref of tree(s) data for this model
-shape_params => hashref of parameters
('shape' => 'alpha',
'gamma' => $g,
'r' => $r,
'f' => $f
)
OR
( 'shape' => 'beta',
'p' => $p,
'q' => $q
)
-likelihood => likelihood
-num_site_classes => number of site classes
-dnds_site_classes => hashref with two keys, 'p' and 'w'
which each point to an array, each
slot is for a different site class.
'w' is for dN/dS and 'p' is probability

Title : dnds_site_classes
Usage : $obj->dnds_site_classes($newval)
Function: Get/Set dN/dS site classes, a hashref
with 2 keys, 'p' and 'w' which point to arrays
one slot for each site class.
Returns : value of dnds_site_classes (a hashref)
Args : on set, new value (a scalar or undef, optional)
Title : get_pos_selected_sites
Usage : my @sites = $modelresult->get_pos_selected_sites();

being a site, 4 values,
site location (in the original alignment)
Amino acid (I *think* in the first sequence)
P (P value)

Returns : count of the number of sites stored
Args : $site - site number (in the alignment)
$aa - amino acid under selection
$pvalue - float from 0->1 represent probability site is under selection according to this model

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.
