[Chimera-users] Problem with electrostatic surface

Hi Benedikt,
You still need to show the surface of your molecule, e.g. with command "surface #0 & protein" (or "surface #1 & protein" since they are the same atomic coordinates).  After you do that, it will be listed in the menu of choices of what surface to color in the Surface Color dialog.
I hope this helps,

I ran the PDB2PQR tool as described in the user guide and obtained a PDB2PQR file. With that, I ran the APBS tool and obtained a .dx file. As described, the Surface Color panel opens automatically, but here I am unable to choose my structure file for "color surface" (s. attachment 1). I can only choose the .dx file, which does not work. All three models obtained during this process are opened in the model panel though (s. attachment 2).
