Hello
I am running mmpbsa in amber18 using the following command" MMPBSA-1.py -O -i mmpbsa.in -o mmpbsa.dat -do final_mmpbsa.dat -sp com_solvated.prmtop -cp com.prmtop -rp ras.prmtop -sp raf.prmtop -y md.crd"
But I am encountering an error which says "
Loading and checking parameter files for compatibility...
