Inferring the performance of the Gibbs sampler on 8 Vertebrates genomes. See the text for detailed description of the data and the method. Left: The number of SCJ operations of the 14 edges of the evolutionary tree in the samples of the Gibbs sampler. Samples were collected after each 10000 Gibbs sampling steps, 1000 samples were collected. For readability, the numbers of SCJ operations falling onto edges have been shifted such that the average of them be 20, 40, 60,... 280. Right: Autocorrelations of the number of SCJ operations on edges in the samples. One unit on the first axis means 10000 Gibbs sampling steps.
