fftavg 2248.img
This program reads a set of images (all the same size), does an FFT of each, then averages them to generate an approximate power spectrum. This functionality is already incorporated into ctfit, but this program may still be useful for offline calculations. An x/y plot of the power spectrum is dumped to stdout, and the averaged image is output to fftavg.tnf (a complex MRC file)
