Hi all - anybody know the answer, or can tell me where to look:
Regarding that oft-stated rule-of-thumb from the 60s (Blow? Crick?), that a 1% change in cell parameters causes a 3% change in intensities: is there an equivalent statement to be made about how phases change with increasing non-isomorphism - and related to that, at what point do maps become unrecognisable?
Or another way to ask this: how isomorphous must two datasets be for a phase transplant from one to the other to be valid?
Cheers Frank
