Good morning, my question is the following. I have to calculate the roughness with its error bar from images with 3 nm height islands on silicon oxide. Unfortunately, also some crystals are present. They are quite height and not properly scanned by the afm. The roughness I have to calculte should not be referred to those crystals so I decided to use masks to get rid of them.
My problem is that with masks I cannot get a roughness value with its error bar. If I use in Gwyddion the option "Calculate row/column statistical function" there is not the possibility "Exclude masked region". I can get the roughness from the other option "Statistical quantities" but again no error bar. How can I get a roughness value with error bar even if I have to use masks to get rid of crystals?
