  1. When p-value was below 0.1 in SLAC, FEL, MEME and the posterior probability was above 0.9 in FUBAR, positive selection pressure signals were considered to acceptable. Positively selected sites were confirmed when positive selection pressure signals were identified by at least two methods. “∞” represents numerical infinity
