Some recently released PDB entries (for instance 3u57) have structure factor files that contain map coefficients. We think this is a really good idea because it means that final maps as interpreted by the crystallographer will then be archived and available.

But there is a problem converting such files to mtz with the current cif2mtz program; indeed we raised this on the bb in September:

To get around this we produced a quick-fix patch for cif2mtz that is available at:
