Posterior probabilities for species trees 1 and 2 (fig. 7) for the gibbon datasets under different priors in the relaxed-clock models. Two replicate runs are presented for each of nine priors, specified by locusrate = 1 0 0 5 iid, clock = 2 ${\alpha }_{\overline{\nu }}{\beta }_{\overline{\nu }}$ 5 iid G, where the parameters are given as (${\alpha }_{\overline{\nu }}$, ${\beta }_{\overline{\nu }}$) = (1, 100), (2, 200), (10, 1000), (1, 10), (2, 20), (10, 100), (1, 1), (2, 2), and (10, 10). Note that the prior $\overline{\nu }\sim \mathrm{G}({\alpha }_{\overline{\nu }},{\beta }_{\overline{\nu }})$ has the mean ${\alpha }_{\overline{\nu }}/{\beta }_{\overline{\nu }}$ and the variance ${\alpha }_{\overline{\nu }}/{\beta }_{\overline{\nu }}^2$. The GTR+$\mathrm{\Gamma }$ substitution model is assumed.
