Algorithm accuracy vs. fragment divergence. Sets of 2, 3, 5, 10 genomes were sampled randomly from a set of 1055 completed bacterial chromosomes, and experiments were conducted as described in Materials and Methods. Trials were conducted with 400- and 800-nt long fragments. Classification accuracy for the majority of genome pairs above overall divergence 1 is in the high performance range (accuracy > 0.9), while above divergence 3 accuracy is above 0.9 for over 95% of the trials. Results for Bayesian posterior distribution sampling were not significantly different (Additional file 3).
