I am performing protein-protein docking using Autodock tools (following https://www.researchgate.net/post/Problem_in_using_Cygwin_commands_for_running_Autodock). I have tried by adding Kollman charges to both proteins and gasteiger charges to one protein, but the problem appears while I run Autogrid, and showing the error shown in the attached screenshot. I am not able to interpret this error. Can anyone tell me where I went wrong in doing the protein-protein docking and how can I correct it?

The proteins I have used here are Apoptosis-inducing factor (AIF) and ATP synthase protein 6 (ATP6) from Dictyostelium discoideum.

Note: I have modeled both the protein structures via homology modeling.
