[chimerax-users] B-factor and error in distance measurements

I have two structures of a protein solved to different resolutions, one pretty good and the second not so good, and I want to compare distances between congruent atoms in the structures. It occurred to me that I have no idea if the differences in the distances are within the positional error of the atoms or not. Therefore, is there a way to propagate the positional uncertainty in the B-factors into a linear distance uncertainty? Sincerely, Charles
