ADL: Help with adding atomic parameter

Hi Rik,

unfortunately, adding new types to Vina is not as simple as it is with AutoDock4.
My recommendation is to pick the replace your atom type with the closest element (especially for the vdW radius) that is already in the force field.

Besides, if your atom is not establishing direct interactions with the receptor (i.e., it's fully substituted/coordinated by other atoms) the choice of the atom type would have a rather minimal impact on the docking outcome.

Hope this helps,
