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:

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
