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,
