[Chimera-users] Electrostatical surface of a virus

I need to visualize the electrostatic surface of a virus. I don't know how to do it. I was thinking in the following sequence of instructions: 1. Use the DelPhiController to generate the potential map (*.phi) for the asymmetric unit. 2. Use Multiscale Models tool to generate the 60-related units. Is this a logic sequence ? Any hint would be appreciated. Thank you.
