ADL: Some questions regartding autodock-vina: partial charges model plus ligand and receptor preparation scripts

Vina and Autodock4 are different programs and different scoring functions.
Vina, unlike autodock4, does not use electrostatics or partial charges - it
will ignore such values. I use the scripts with the "4", or "42" if
available, I think they indicate the version of autodock they are
designed to work with.

Best regards,
