Hello Johan and Natesh, There is more info about the terminology in this article: https://doi.org/10.1038/s41586-024-07215-4 In brief, yes, "Coulomb potential map" or "electrostatic potential map" is most correct (as far as I remember). But "cryoEM map" is widely accepted as a shortcut, and is

Hi Natesh; I don't know that "density" is necessarily inappropriate: the map gives potential for each voxel, so potential per volume. I'd think that's a density. Unsure about "cryoEM density" though, but this may be a matter of how the phrase is delineated. I often look at green (and red)

Dear Gloria, Already the wonderful chimera, phenix and ccpEM and other excellent softwares have been highlighted for your requirements. Along with that, I would like to suggest a small correction. It is not correct to say 'cryoEM density' or 'cryoEM density map'. X-ray Crystallog

Hi Gloria, Guillaume already mentioned emplace_local, so I’ll just mention that if you get a recent nightly build of Phenix and the latest version of ChimeraX (plus the Phenix UI plugin from the toolshed), you can tell it your map has symmetry, place a monomer, and then it will detect the symme
