Problem with electrostatic surface
Dear Chimera team, I am trying to display color the surface of my molecule according with Poisson-Boltzmann electrostatics using Chimera 1.14. 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). Do you have any idea on how to fix this? Thank you very much in advance and keep up the great work!

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, Elaine ----- Elaine C.
