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.

I have been eagerly awaiting a response to this. A few years ago I had
asked a related question about how electron diffraction patterns could
be scaled in reciprocal units. The response at that time was that it was
required to set a property, that was not accessible through the macro
language. Is there a solution now? If the info could be retained when
saved as TIFF, it would help a lot.
