Hi Greg, I see this is a bit confusing. You need a surface to color. Usually this is a molecular surface. You would make such a surface by opening an atomic model (e.g. PDB file) and using menu entry Actions / Surface / Show. Then you would select that surface in the Surface Color dialog and press the Color button. If you don't have any molecular surface and just want to see an isopotential surface then open the file, close the surface color dialog and then use menu entry Tools / Volume Data / Volume Viewer to show the volume dialog. Click on the apbs file name shown in the volume dialog. Tom

Hi, I'm trying to load an electrostatic potential file (.dx) that I created with the online APBS tools. Nothing displays however when I select "color" from the "surface color" dialog. Is this feature working in the current version?

I'm using version 1.4.1. The potential file is http://dl.dropbox.com/u/5763765/pot.dx.gz

Thanks, Greg
