Distinguished Sir or Madam
I'm trying to use MCPB.py for performing parameterizations for both the metalloprotein and organometallic compound systems. I followed the steps to prepare the PDB and mol2 files for the non-standard residues and metal ions in the tutorial and there was errors in the first step of generating the PDB, Gaussian and fingerprint modeling files.
Here are my error messages:

***Creating the small model...
It contains the residue 146-GLN as sidechain coordinated.
It contains the residue 2475-F31 as normal.
It contains the residue 2476-NI1 as normal.
Totally there are 125 atoms in the small model.

KeyError: '2'
This problem confused me. I tried to rebuild the model and repeat the preparations in the tutorials. It seems to be that the number of electrons in the model is wrong. But I don't know how to solve it.
Could someone help me out of the problem? Any response will be highly appreciated!
Yours,
Wu Jue
