Dear all,


I want to solvate then minimize (few steps) a structure with a zinc (Zn2+)

>From what I saw in the manual, zinc parameters are available in the actual
version of the amber force field in chimera. However, I am stuck with
troubles. When I solvate I have the following message:

Could not determine charges for pre-existing solvent from added solvent for:
Zn Zn

What do I do wrong?


All the best,
