Dear amber users,

I am trying to calculate binding energies using MMGBSA for a complex with
glycosaminoglycan and Mg2+.

I keep running into the error,
CalcError: /users/work/czarek/amber16/bin/sander failed with prmtop
complex.top!
Error occured on rank 0.
Exiting. All files have been retained.


The input file for the MMGBSA.

Input file for GB/decomposition calculation
&general
startframe=1, endframe=10, interval=1,
verbose=2, keep_files=0,
/
&gb
 igb=2,
/
&decomp
idecomp=2
/

the frcmod.MG file that I used for MD simulations

Mg2+ ion parameters

MASS
MG 24.3

NONBON
  MG 1.5545 0.00295 MG


I am using AMBER 16 for MD calculations.

I would be thankful for any sort of help!

best regards
Urszula
