For those who are interested, I have places a small package for doing fft's on minc volumes here: http://www.bic.mni.mcgill.ca/~rotor/distro/tgz/mincfft-1.1.tar.gz I have also built a debian sarge package for it here: http://www.bic.mni.mcgill.ca/~rotor/distro/deb/mincfft-1.1-linux-2.6-intel.deb I'd be interested in usage/wants-needs reports for those who use it. Thanks Andrew
