WhiIe i was trying to build bonded model for ligand binding metalloprotein
with MCPB.py with zinc ions, I got an error.
I run the following command "MCPB.py -i 6ye2.in -s 1" and I got the
following error:
chg = int(round(chargedict[ionname], 0))
KeyError: 'HZ2'
How can I solve this?
Thank you
this is 6ye2.in input file:
original_pdb 6ye2_fixed_H.pdb
group_name 6ye2
cut_off 2.8
ion_ids 4018
ion_mol2files 6ye2_ZN.mol2
naa_mol2files 6ye2_ligand.mol2 6ye2_WAT.mol2
frcmod_files 6ye2_ligand.frcmod
large_opt 1
The terminal Output:

The input file you are using is : 6ye2.in
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
The following is the input variable you have:
The variable ion_ids is : [4018]
The variable ion_info is : []
The variable ion_mol2files is : ['6ye2_ZN.mol2']
The variable original_pdb is : 6ye2_fixed_H.pdb
The variable add_bonded_pairs is : []
The variable add_redcrd is : 0
The variable additional_resids is : []
The variable anglefc_avg is : 0
The variable bondfc_avg is : 0
The variable chgfix_resids is : []
The variable cut_off is : 2.8
The variable force_field is : ff19SB
The variable frcmod_files is : ['6ye2_ligand.frcmod']
The variable gaff is : 1
The variable group_name is : 6ye2
The variable ion_paraset is : 12_6 (Only for the ions using the nonbonded
model).
The variable large_opt is : 1
The variable lgmodel_chg is : -99
The variable lgmodel_spin is : -99
-99 means program will assign a charge automatically.
The variable naa_mol2files is : ['6ye2_ligand.mol2', '6ye2_WAT.mol2']
The variable scale_factor is : 1.0
ATTENTION: This is the scale factor of frequency. The
force constants will be scaled by multiplying the square
of scale_factor.
The variable smmodel_chg is : -99
The variable smmodel_spin is : -99
-99 means program will assign a charge automatically.
