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 -lp raf.prmtop -y md.crd"
But I am encountering an error which says "Loading and checking parameter files for compatibility...

    raise SelectionError('Invalid selection! Integers expected.')
SelectionError: Invalid selection! Integers expected."
And the input file MMPBSA content is "
  endframe = 10000,
  verbose = 1,
  strip_mask = ":WAT:CL:CLO:IB:K:LI:MG:NA:NB",
  igb = 5, saltcon = 0.100,
  istrng = 0.100,
  idecomp = 1, print_res = ":1-77", dec_verbose = 1,
How to rectify this kindly help as I am badly stuck in this.
Thank you,
