This problem you're facing seems related to #136. Can you change the lightRGB[0] to int(lightRGB[0]) and so on?

You may also want to check the following script: https://tiny.cc/XDrugPy. It contains a module for docking with AutoDock Vina. It doesn't supersedes the plugin you're trying to use because only works with Vina.

@camattelaer, if the plugin works as expected after the changes, we can manage it into this repository.

Kind regards

@pslacerda Hello, I encountered the same problem and tried your suggestion. But I'm using python3.9, not python3.12.
The source field of Pmwcolor.py is:
return (
'#%04x%04x%04x' % (lightRGB[0], lightRGB[1], lightRGB[2]),
'#%04x%04x%04x' % (darkRGB[0], darkRGB[1], darkRGB[2])
)
I modified it to:
return (
'#%04x%04x%04x' % (int(lightRGB[0]), int(lightRGB[1]), int(lightRGB[2])),
'#%04x%04x%04x' % (int(darkRGB[0]), int(darkRGB[1]), int(darkRGB[2]))
)
What intrigued me was that this modification seemed to be targeted at the PyMOL software rather than the autodock_plugin.py plugin.
After the modifications were completed, the plugin opened normally.
autodock_plugin seems not to have been updated for about two years. I am interested in which object the error is associated with, pymol or plugin. But thank you for your contribution.

Honestly, I don't know why it works, I just read the error. RGB hexadecimal RGB numbers aren't 12 characters long. The correct answer is this: #122.

thanks.
