[AMBER] RESP charge fitting error in MCPB.py

Dear All,
I am trying to calculate the force field parameters for my metal and its active site residues using MCPB.py.
In the first step, I got the small and large models for Gaussian optimization. I verified the charges and multiplicity of both and optimized the geometry.
MCPB.py -i 1OKL.in -s 1
Next, I generated the force field parameters for those models using MCPB.py -i 1OKL.in -s 2.
Further, I have tried to do the RESP charge fitting, there I got an error.
I suspect that while generating resp2.chg file, there is no space between these two strings.
Anyone kindly help me to solve this issue.
Thank you.
