Hello,
I have a question. I am working with a set of vesicular stomatitis sequences, I performed SLAC , IFEL, FEL and I did not find a signal of positive selection only negative, however when I tried with Gabranch I got some branches with dn/ds more than 1.00. How must I interpret this results? As a positive selection only at population level?



Thank you for your Help,

Lauro.
