You usually need to play with the contour level, map radius, and location to get a good view. Also, check the terminal window for any error messages.

When I load the map as an .mrc file into coot, it looks fine, but when I convert this mrc file to mtz using either mrc2mtz (from https://www2.mrc-lmb.cam.ac.uk/groups/murshudov/content/em_fitting/em_fitting.html) or using phenix.map_to_structure_factors, I do not see any density when this file is opened in coot0.83 using the Open MTZ option. Please advise. Thanks for your help! Sincerely, Ali Khan
