Dear Amber users
I am facing a problem using MMPBSA.py while calculating GBSA
 MMPBSA.py -O -i mmpbsa_e.in -o result_e.dat -sp topol_wild_nowat.prmtop
-cp com.prmtop -rp rec.prmtop -lp ligand.prmtop -y wild_fixedcorrupted.nc
Loading and checking parameter files for compatibility...
cpptraj found! Using /opt/amber18/bin/cpptraj
mmpbsa_py_energy found! Using /opt/amber18/bin/mmpbsa_py_energy

  File "/opt/amber18/bin/MMPBSA.py", line 99, in <module>

    from alamdcrd import MutantMdcrd, GlyMutantMdcrd
ModuleNotFoundError: No module named 'alamdcrd'
Exiting. All files have been retained.

The input file I used is as follows:-
  startframe=1, endframe=8060, interval=100
  strip_mask= :WAT,Na+,
 igb=5, saltcon=0.150

I am not getting why this error is arising and how can I fix it. Could you
please give me any suggestions to fix this error?
Thanks in advance.
