Googling for how is b-factor related to atom positional uncertainty says "The B-factor is mathematically related to the mean squared displacement of an atom from its average position. Specifically, B = 8π²〈u²〉, where 〈u²〉 is the mean squared displacement. " Tom

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?
