  1. p and q are parameters of the β distribution. f is the proportion of sites assigned to an individual ω (= dN/dS) category or to a β distribution with shape parameters p and q, f1 = 1 – f0. Sites inferred under selection at the 90% level are listed in bold, and those at the 95% level are marked with an asterisk.
