 Hi again Bill, I did a git pull and recompiled MMPBSA.py from the src/mmpbsa_py/ folder. However, the problem persists: Reading command-line arguments and input files...
Loading and checking parameter files for compatibility...
  File "/usr/local/amber/bin/MMPBSA.py", line 641, in <module>
    [numframes, numframes_nmode], mut_str)
  File "/usr/local/amber/bin/MMPBSA_mods/output_file.py", line 384, in write_binding_output
    if INPUT[solv]:
KeyError: 'rismrun_std'
Error occured on rank 0.
Exiting. All files have been retained.
The calculation itself finished successfully. Best regards, Åge
