[AMBER] problem in MCPB.py

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:

***Selected Metal ion NI is atom 37834 in residue 2476-NI1

146-GLN.OE1 is in 2.8 Angstrom of or set bonded (in the input file) to (one of) these metal ions

2475-F31.NB is in 2.8 Angstrom of or set bonded (in the input file) to (one of) these metal ions

2475-F31.NC is in 2.8 Angstrom of or set bonded (in the input file) to (one of) these metal ions

***The following residues are in the Metal Site:

Residue 146-GLN

Residue 2475-F31

Residue 2476-NI1

***The small model contains the following residues:

[146, 2475, 2476]

***The large model contains the following residues:

[145, 146, 147, 2475, 2476]

***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.

Traceback (most recent call last):

    AtNum = Atnum[gatm.element]

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!
