SYNOPSIS

use Bio::Tools::Run::Phylo::Hyphy::SLAC;

use Bio::TreeIO;
my $alignio = Bio::AlignIO->new(-format => 'fasta',
-file => 't/data/hyphy1.fasta');

DESCRIPTION

This is a wrapper around the SLAC analysis of HyPhy ([Hy]pothesis Testing Using [Phy]logenies) package of Sergei Kosakowsky Pond, Spencer V. Muse, Simon D.W. Frost and Art Poon. See http://www.hyphy.org for more information.

Support

Please direct usage questions or support issues to the mailing list:

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

Default Values

Valid and default values for SLAC are listed below. The default values are always the first one listed. These descriptions are essentially lifted from the python wrapper or provided by the author.

INCOMPLETE DOCUMENTATION OF ALL METHODS

run

 Title   : run
 Usage   : my ($rc,$results) = $slac->run($aln);
 Function: run the slac analysis using the default or updated parameters
           the alignment parameter must have been set
