Hi yeti, it seems I found an issue regarding the 2D-FFT transformation in the current Gwyddion release (v2.34).
I have (again) data with a physical dimension of 1 x 1 q-microns with a pixel aspect ratio of 2:1. Performing standard operations like leveling etc everything works fine. But when continuing with FFT transformation the output relates to the aspect ratio of the pixel size. Not only in the aspect ratio of the displayed image is falsified but also its physical dimension. Here, the xrange goes from [-256:256] invers microns, but the yrange is [-126:126] invers microns. This should be equal. Fruther, the toggle menu in the left corner (change between physically square and pixelwise square) does not respond. Is there a chance to fix this?
