MrBayes on CyVerse UK

Community rating: ?????

This is MrBayes version 3.2.6 on the CyVerse UK hardware (12 cpus, 256 GB per job). It is software for Bayesian analysis of molecular sequences using MCMC. See http://mrbayes.sourceforge.net/manual.php for more info.

Quick Start

This is a fairly simple app in terms of inputs and outputs, all it needs is a Nexus file with a sequence alignment and a .bb file with a MrBayes block in it; this contains a sequence alignment and all options necessary for the program. See the example file in the example data. Also see the detailed guide in the manual (http://mrbayes.sourceforge.net/mb3.2_manual.pdf) pp 109.
