<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Dear Chimera team,<br><br>I am having a bit of trouble reading a file into Chimera. Currently I am using Gamess to run DFT calculations and I can open these files in MacMolPlt which allows me to display orbitals or plot electrostatic potential surfaces. I can export the 3D surface data however I can't get Chimera to read the 3D grid files. Can you help me? I attached the file format info below with an exported density file and electrostatic potential map. I am really trying to use Chimera for all my graphics needs wether it be viewing surfaces or orbitals from DFT calculations or looking at electron density maps from crystal structure data. If I could convert the 3D surface data files below into ccp4 or cns formated files that should also work for Chimera I just haven't found a way to do this yet.<div><br>Thanks in advance,<br>Dave<br><br>**********************************************<br>David M.
