I recently installed PI 1.2.3.2016 (and PFE 11.6.1) on our JEOL 8530F. I loaded a previous acquisition file for square beam maps (150x150 pixels, 9500X or ~10x10um). However, now the 'Acquisition' window says the dimensions are going to be 12.54 x 9.06 um -- I ran the maps and the images do come out elongated in the X direction. Is there a way that I can force the pixel size to be square again for beam maps?
