If you haven’t already, download and install BEAST following these instructions.
Note: This tutorial assumes a basic knowledge of molecular phylogenetics and the models and terminology used in the field.
For this tutorial, the Mac OS X version will be shown but the Linux & Windows versions will have exactly the same layout and functionality.
At the top of the window is an option called , specifies how often each operator is applied relative to each other.
Some parameters have very little interaction with the rest of the model and as a result tend to be estimated very efficiently - an example is the Firstly we have the Length of chain.
This is the number of steps the MCMC will make in the chain before finishing.
How long this should be depends on the size of the dataset, the complexity of the model and the quality of answer required.
