NAME¶
Bio::Tools::Run::Phylo::PAML::Yn00 - Wrapper aroud the PAML program yn00
VERSION¶
version 1.7.3
SYNOPSIS¶
use Bio::Tools::Run::Phylo::PAML::Yn00;
use Bio::AlignIO;
my $alignio = Bio::AlignIO->new(-format => 'phylip',
-file => 't/data/gf-s85.phylip');
my $aln = $alignio->next_aln;
my $yn = Bio::Tools::Run::Phylo::PAML::Yn00->new();
$yn->alignment($aln);
my ($rc,$parser) = $yn->run();
while( my $result = $parser->next_result ) {
my @otus = $result->get_seqs();
my $MLmatrix = $result->get_MLmatrix();
# 0 and 1 correspond to the 1st and 2nd entry in the @otus array
my $dN = $MLmatrix->[0]->[1]->{dN};
my $dS = $MLmatrix->[0]->[1]->{dS};
my $kaks =$MLmatrix->[0]->[1]->{omega};
print "Ka = $dN Ks = $dS Ka/Ks = $kaks\n";
}
DESCRIPTION¶
This is a wrapper around the yn00 (method of Yang and Nielsen, 2000) program of PAML (Phylogenetic Analysis by Maximum Likelihood) package of Ziheng Yang. See http://abacus.gene.ucl.ac.uk/software/paml.html for more information.
This module will generate a proper yn00.ctl file and will run the program in a separate temporary directory to avoid creating temp files all over the place and will cleanup after itself.
Default Values¶
See the Bio::Tools::Run::Phylo::PAML::Codeml module for documentation of the default values.
ATTRIBUTES¶
program_name¶
Title : program_name Usage : $yn00->program_name() Function: holds the program name Returns: string Args : None
program_dir¶
Title : program_dir Usage : $yn00->program_dir() Function: returns the program directory, obtained from ENV variable. Returns: string Args :
error_string¶
Title : error_string Usage : $obj->error_string($newval) Function: Where the output from the last analysus run is stored. Returns : value of error_string Args : newvalue (optional)
alignment¶
Title : alignment
Usage : $codeml->align($aln);
Function: Get/Set the L<Bio::Align::AlignI> object
Returns : L<Bio::Align::AlignI> object
Args : [optional] L<Bio::Align::AlignI>
Comment : We could potentially add support for running directly on a file
but we shall keep it simple
See also: L<Bio::SimpleAlign>
no_param_checks¶
Title : no_param_checks
Usage : $obj->no_param_checks($newval)
Function: Boolean flag as to whether or not we should
trust the sanity checks for parameter values
Returns : value of no_param_checks
Args : newvalue (optional)
save_tempfiles¶
Title : save_tempfiles Usage : $obj->save_tempfiles($newval) Function: Returns : value of save_tempfiles Args : newvalue (optional)
outfile_name¶
Title : outfile_name
Usage : my $outfile = $codeml->outfile_name();
Function: Get/Set the name of the output file for this run
(if you wanted to do something special)
Returns : string
Args : [optional] string to set value to
tempdir¶
Title : tempdir Usage : my $tmpdir = $self->tempdir(); Function: Retrieve a temporary directory name (which is created) Returns : string which is the name of the temporary directory Args : none
METHODS¶
new¶
Title : new
Usage : my $obj = Bio::Tools::Run::Phylo::PAML::Yn00->new();
Function: Builds a new Bio::Tools::Run::Phylo::PAML::Yn00 object
Returns : Bio::Tools::Run::Phylo::PAML::Yn00
Args : -alignment => the L<Bio::Align::AlignI> object
-save_tempfiles => boolean to save the generated tempfiles and
NOT cleanup after onesself (default FALSE)
run¶
Title : run
Usage : $yn->run();
Function: run the yn00 analysis using the default or updated parameters
the alignment parameter must have been set
Returns : 3 values,
$rc = 1 for success, 0 for errors
hash reference of the Yang calculated Ka/Ks values
this is a set of pairwise observations keyed as
sequencenameA->sequencenameB->datatype
hash reference same as the previous one except it for the
Nei and Gojobori calculated Ka,Ks,omega values
Args : none
get_parameters¶
Title : get_parameters Usage : my %params = $self->get_parameters(); Function: returns the list of parameters as a hash Returns : associative array keyed on parameter names Args : none
set_parameter¶
Title : set_parameter
Usage : $codeml->set_parameter($param,$val);
Function: Sets a codeml parameter, will be validated against
the valid values as set in the %VALIDVALUES class variable.
The checks can be ignored if on turns of param checks like this:
$codeml->no_param_checks(1)
Returns : boolean if set was success, if verbose is set to -1
then no warning will be reported
Args : $paramname => name of the parameter
$value => value to set the parameter to
See also: L<no_param_checks()>
set_default_parameters¶
Title : set_default_parameters
Usage : $codeml->set_default_parameters(0);
Function: (Re)set the default parameters from the defaults
(the first value in each array in the
%VALIDVALUES class variable)
Returns : none
Args : boolean: keep existing parameter values
cleanup¶
Title : cleanup Usage : $codeml->cleanup(); Function: Will cleanup the tempdir directory after a PAML run Returns : none Args : none
io¶
Title : io Usage : $obj->io($newval) Function: Gets a L<Bio::Root::IO> object Returns : L<Bio::Root::IO> Args : none

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.
