Mrbayes
==============================

Introduction
~~~~~~~~
MrBayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models. MrBayes uses Markov chain Monte Carlo (MCMC) methods to estimate the posterior distribution of model parameters. MrBayes is available both in a serial version ('mb') and in a parallel version ('mb-mpi') that uses MPI instructions to distribute computations across several processors or processor cores. The serial version does *not* support multi-threading, which means that you will not be able to utilize more than one core on a multi-core machine for a single MrBayes analysis. If you want to utilize all cores,you need to run the MPI version of MrBayes. Note: 'mb-mpi' in this version of the container does not run across multiple nodes (only within a node). This is a bug in the container (upstream).

    module load mrbayes

Example job
~~~~~
.. warning::
    Using ``#!/bin/sh -l`` as shebang in the slurm job script will cause the failure of some biocontainer modules. Please use ``#!/bin/bash`` instead.
