Thanks Ross,
I did what u suggested but it gave me a warning:
WARNING: expected Improper Torsion PK>0 (-2.820000)
WARNING: expected Improper Torsion PHASE=180 (0.000000)
for all the four torsions. I was just wondering if these are some
harrmful warnings or I can neglect them. I took them from ur thesis.
Have there been updates in the parameters that you published in your
thesis? I also have 4 CYM coordinating a zinc atom.
thanks a lot in advance,
sincere rgds,
Nitin
