The MMPBSA.py script is consistently crashing while analyzing
_MMPBSA_complex_gb.mdout. The following is written in the .mdout

 Reading parm file (com.top)
title:


        mm_options: e_debug=2
        mm_options: gb=2
        mm_options: rgbmax=25.000000

The job got crashed after processing 1st frame.

In VMD I have visualized _MMPBSA_complex.pdb, the atoms 3044, 3051, and 3055
are not bonded to C atom. Why it is showing this error?



Thanks,
