WebHi. Finding positively selected sites with great accuracy is very tricky. To find positively selected sites within certain lineage, you have to mark that lineage as foreground in the tree by labeling it with "#1" or "$1". Selected genes can be predicted using LRT test and multiple hypothesis testing using BC or FDR @ 5 or 1% level of significance.
