I have a series of time-lapse imaging data where I'd like to analyze the FFT of each frame in the stack and do some filtering there, and subsequently inverse FFT the stack back to the image domain. Hoping Wayne can work his magic!

> Upgrade to the latest daily build (1.51o20) and you can use simple macros to do FFTs and Inverse FFTs on the images in a stack. I included two macros. The first runs the “FFT” command on the images in the T1 Head sample stack, saving the output in a virtual stack. The second runs the “Inverse FFT” command on the virtual stack. You will need to modify the second line of the first macro so that ‘dir’ points to an empty folder.
