Dear Friends
I have performed the simulation for the protein-ligand complex. I would like to perform the MMPBSA analysis (since it was the first run, I started with first 10 frames). I am getting the following error.
Input:
Input file for running PB and GB
&general
endframe=10, verbose=1,
receptor_mask=':1-1082',
ligand_mask=':1085',
keep_files=2, interval=1,
/
&gb
igb=2, saltcon=0.100
/
&pb
istrng=0.100,

All files have been retained for your error investigation:
You should begin by examining the output files of the first failed calculation.
Consult the "Temporary Files" subsection of the MMPBSA.py chapter in the
manual for file naming conventions.
Please suggest me how to recover from this error.
Thanks
