Hello,

I did a branch site REL analysis from datamonkey and had the following results:
Found 1 branches under episodic diversifying selection at p<0.05
Branch A (A is the name of one of my species)
Corrected p-value 0.002
w+ 10,000.00
Pr[w=w+] 0.00, Pr the proportion of sites inferred to be evolving at w+ along this branch.
I need help in understanding while Pr is zero when there is evidence of episodic diversifying selection on the branch.  I expected Pr>0 since there are sites under positive selection according to the results.

Hi there,

Pr[w=w+] = 0.00 up to two digits of precision (i.e. it is not exactly zero). If you look at the CSV results file from the analysis, you will have access to more decimal places.

Hello Sergei,

Thanks for the clarification.
