Isn't it simply FSC? Then according to Wikipedia the citation goes back
even further, 1986 !

Hi,
Bart Hazes' sftools program does map correlation in resolution shells in this
way, and may even have been doing it before 1996 if I'm remembering correctly.

Dear Phil,
Gerard Bricogne pointed out a long time ago that the clearest comparison
between two sets of phases is the complex correlation coefficient between two
"best" structure factors ( m F exp(i phi) ) - this is equivalent to map
correlation, but can be analysed in resolution bins.

The papers you are looking for are:
Crick FHC & Magdoff BS (1956)."The theory of the method of isomorphous
replacement for protein crystals. I", Acta Crystallogr. 9, 901-908.

Obviously it depends on degree of isomorphism - the Riso plot from
SCALEPACK gives you a measure..
It would be hard to sort out phase change due to non-isomorphism v phase
change from error - in measurements, substructure, etc
But a practical guide - when doing phase extension from a SAD set of p
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-i
