You mean something like the animation at the top of this web page? http://bl831.als.lbl.gov/~jamesh/fastBragg/ This program is a relative of nearBragg, which Dale already mentioned. -James Holton MAD Scientist On Jan 6, 2012, at 5:44 PM, Jacob Keller wrote: > Actually, as a way to make this

The CCP4 program that makes the "label map" you are looking for is SFALL. It can be told to make a .map file where each grid point is still a floating-point number, but instead of the usual electron density it "encodes" the residue number, atom number, etc. The OVERLAPMAP program knows how to de

Actually, Jeff, the problem goes even deeper than that. Have a look at these Wilson plots: http://bl831.als.lbl.gov/~jamesh/wilson/wilsons.png For these plots I took Fs from a unit cell full of a random collection of atoms, squared them, added Gaussian noise with RMS = 1, and then ran them back

Based on the simulations I've done the data should be "cut" at CC1/2 = 0. Seriously. Problem is figuring out where it hits zero. Alternately, if French & Wilson can be modified so the Wilson plot is always straight, then the data don't need to be "cut" at all. As for the "resolution of the st
