Figure 5

Underestimate of Bayesian branch lengths with different branch length priors. (a) Percentage that branch lengths were underestimated for 1 kb datasets simulated on 4-taxon trees with equal branch lengths using the HKY model with a transition/transversion ratio of 2 and equal base frequencies, and analyzed using MrBayes with an exponential prior on branch lengths of mean = 1. (b) Identical to (a) but analyzed with a uniform prior on branch lengths (bounds of 0-1).
