Hi Saif, Can you please show us the commands you used in PyMOL to load the data and generate the map? (Also, can you send me a copy of the map and structure?) Has anyone else seen this problem?
I've looked over a few CCP4 maps in PyMOL, Maestro, and Coot side-by-side, and at various contours, they all look virtually identical. There are slight differences, probably due to algorithmic deviations, but they look good to me. In PyMOL: # mimic Coot set orthoscopic set line_width, 5 # get the data fetch 1cll, async=0 fetch 1cll, type=2fofc, async=0 # create the map; carve 2.5 Ang from the polymer isomesh 1cll_map,1cll_2fofc, 1.06, poly, carve=2.5 # find example residue orient i. 78 # color color magenta, e. N color tv_yellow, e. C In Coot: * Fetch 1CLL and its map from EDS * zoom to residue 78 * scroll to 1.06 sigma What do you see here? Cheers, -- Jason On Tue, Oct 26, 2010 at 9:50 AM, S.
