I am facing similar issue to those discussed elsewhere on ResearchGate regarding Autodock 4:
https://www.researchgate.net/post/Does_anybody_has_a_parameter_file_for_platinum_in_autodock https://www.researchgate.net/post/How_to_add_Europium_atomic_parameter_in_autodock
It solved my problem with Autodock 4.2
I am however unable to figure out how to solve the same problem faced with Autodock Vina
Any idea on how to modify/update Vina's library so that to include/add Pb atomic parameter, for instance ?
Thanks
