Markov Chain Monte Carlo Coalescent Program
Version 1.2, March 2008
Please send comments to
MCMCcoal is an ANSI C program that implements the Bayesian Markov chain Monte Carlo (MCMC) algorithm
of Rannala & Yang (2003) for estimating species divergence times and population sizes from DNA sequence
alignments at multiple loci. Consult the paper for details of the model assumptions and the theory.
The program can also be used to analyze a sample of sequences from one modern species under the standard
neutral coalescent to estimate theta.

You will need to upload your data file and a control file which contains the parameters you want to run.
Please refer to the
MCMCcoal documention or the
MCMCcoal web page
for more information on the format of these files.
Please note that if you are using an absolute path to
an input file in your control file, it will not be recognized on our system.
If the first line of your control file contains an absolute path to your data file,
it will be modified to just the name of the data
Calculations will be carried out on the BioHPC compute cluster at CBSU. You will receive e-mail notifications when the job is submitted, when it starts, and when it is finished. Output will be available via links embedded in the notification e-mails. For more information about this program and BioHPC interface in general, please visit our Frequently Asked Questions page.
