Dear CCP4,

I have a couple of datasets native and heavy-atom-derivatized. The spacegroup and cell dimensions of all are the same (or very similar). For some reason I cannot merge any of the datasets together. If for example I rescale one native dataset by itself, my Rmerge is about 10%, but when I add 50 images (or so) of another, supposedly isomorphous crystal, my Rmerge goes up to 20%.

I was wondering if anyone has encountered a similar problem or can offer any suggestions. Thanks so much,
Kianoush
