Hi Gabor, I coded "map_correlation" method in cctbx_project/cctbx/miller/__init__.py based on (if I recall it correctly): Acta Cryst. (1993). D49, 530-533 Mean phase error and the map-correlation coefficient Lunin and Woolfson I'm not aware of functionality you described... I guess you can create a clone of "map_correlation" with modifications you want, and add a corresponding method with some (long) self-explicable name and a regression test along with it.

Hi,
I need to calculate the correlation function between two maps, both of them are stored as miller.array objects. There is a map_correlation method, which does something similar to what I want, but this calculates the total correlation coefficient, while what I need is another miller.array with amplitudes = f1*f2 and phases = p2-p1 (where f1, f2 are amplitudes and p1, p2 are phases of map1 and map2, respectively), i.e. not just the sum of these. Is this available somewhere?
There is the additional complication that the hkl-list for map1 and map2 may not be fully identical, but the intersect of the two maps could be taken.
Thanks, Gabor
