Hi all, Sorry for yet another map question: what I'd like to do is be able to generate xplor maps with an explicitly defined size and shape from the command line using phenix. Just choosing a buffer around a selection will result in slightly different sizes for different PDB files, which I'd like to avoid. In my comparisons, having exactly the same dimensions and centering for maps I'm calculating from multiple slightly different variants would be very helpful. Is there a way to do this?
