Bio::Tools::Run::Phylo::Hyphy::Modeltest - Wrapper around the Hyphy Modeltest analysis


  use Bio::Tools::Run::Phylo::Hyphy::Modeltest;
  use Bio::AlignIO;
  use Bio::TreeIO;

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

  my $aln = $alignio->next_aln;

This is a wrapper around the Modeltest 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 for more information.

This module will generate the correct list of options for interfacing with TemplateBatchFiles/Ghostrides/


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.                  - General discussion  - About the mailing lists


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

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.

Default Values

Valid and default values for Modeltest 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.



 Title   : new
 Usage   : my $obj = Bio::Tools::Run::Phylo::Hyphy::Modeltest->new();
 Function: Builds a new Bio::Tools::Run::Phylo::Hyphy::Modeltest object 
 Returns : Bio::Tools::Run::Phylo::Hyphy::Modeltest
 Args    : -alignment => the Bio::Align::AlignI object
           -save_tempfiles => boolean to save the generated tempfiles and
                              NOT cleanup after onesself (default FALSE)
           -tree => the Bio::Tree::TreeI object
           -params => a hashref of parameters (all passed to set_parameter)
           -executable => where the hyphy executable resides
