I have used the model "2 or more dN/dS ratios for branches" in the PAML analysis. However, for some branches, the ka/ks ratio (omega value) is 999.0 (ks is too small). I have checked the alignment and I found nothing wrong there. Should I ignore these branches when interpreting the result? Any advice would be appreciated!

If you do a proper Google search, you would find an answer from Ziheng Yang himself:

They know their programs inside out.
