Konrad, Using crystallographic formats like XPLOR for generic volume visualization is tricky because ultimately the map must be aligned on a grid which passes through the origin. In other words, the grid spacing must include the origin even if the map itself does not. In order to shift t

Hi All, I know there was a question regarding this some time ago, but didn't see any reply saying how to do it or a suggesting a possible workaround. I have a surface coloured by the underlying residues and am wondering if it is possible to colour an additional part of the surface if it's withi
