Dear chimera users,

1) I want to have electrostatic surface of my protein in chimera. To this, I used Tools... Surface/Binding Analysis... Coulombic surface coloring

A new window is opened, but apply bottom is inactive.

2) There are ray command in pymol to obtain better image of molecular structures. Is there a similar command or utility in chimera?

Any help will highly appreciated.

Best wishes,

Leila
