The following command executes BPP with the A00.bpp.ctl control file.
$ bpp --cfile A00.bpp.ctl
In this analysis, the species relationships are fixed therefore the posterior samples stored in the "mcmc.txt" file contain only the theta, tau and phi parameters for the yeast phylogeny.
Below is how the first few lines of the file would look like:

This file is often named "out.txt" and it contains the information printed in the screen while executing the program.
Before the MCMC sampling the program prints in the "out.txt" some information for the input files, i.e.,
The first part of the output contains information regarding the data read from the input files as we show in the species tree inference example.
Performance traits and current estimates of some parameters are printed that can help in evaluating the efficiency of the run
A summary of the posterior sample of the estimated parameters is provided at the end of the output.txt
The most information is the mean and the standard deviation for each of the sampled parameters.
The ESS values help us assess whether the analysis suffers from mixing problems. The larger this number is for each of the parameters the more efficient the MCMC sampling has been (i.e., covering a wider range of possible parameter combinations).

To verify the reliability of the results it would be necessary to repeat the analysis at least one more time.
