You can do cross-correlation when the images are masked; the mask is just ignored. If you want to utilise the mask during cross-correlation, I am not even sure how that would work, but certainly no such thing is implemented. > Also because I am new to Gwyddion I want to confirm with you if I do the > correlation correctly.

How are you using the cross-correlation result if you then apply Mutual crop, which correlates and cuts the images itself? I do not understand what you are trying to achieve.
