Dear AMBER users
I am trying to run a mm-gbsa calculation for a proteing-ligand comples where the ligand has a bromine atom plus an extra-point at the top of the bromine. I got the following error. Does this issue might be related with the extra-point ?
MMPBSA.py -O -i mmpbsa_d.in -o FINAL_RESULTS_MMPBSA.dat -sp D2h_halo-Br-EP_solvated.top -cp D2h_halo-Br-EP.top -rp D2h.top -lp halo-Br-EP.top -y ../../md/md_1.trj
