Hi All,
When I take an FFT of an image, it is obviously using reciprocal space coordinates. However, if I save that FFT to a tif and then reload it later, it loses the reciprocal space and reports the units incorrectly as direct space. Is there a way to set an image back into reciprocal space? I tried, for example, Analyze->Set Scale... Unit of length = nm/c, or changing the distance in pixels from 17.6 to 1/17.6. Better yet, it should retain that info when I save the image.
Any ideas?
Thanks,
