Hello everyone,

I have a problem when I try to include these two variable modifications. So I want to include these:

And this is my approach:
variable_mod03 = -131.040485 n 0 3 0 0 0 0.0 # Met-loss on residue M of protein's N-terminus
variable_mod04 = -89.029920 n 0 3 0 0 0 0.0 # Met-loss + Acetyl on residue M of protein's N-terminus

I also tried it with "nM" instead but I still get a segmentation fault, when I try to run comet. Does somebody know whats wrong?

Thanks for your time and help

Sorry I wasn't aware of this post as I never got notification of it (as well as others since January).  Anyways, for anyone else interested in this topic, it was covered here.
