AFNI program: 3dDFT

Usage: 3dDFT [-prefix ppp] [-abs] [-nfft N] [-detrend] dataset
   where dataset is complex or float valued.

 -abs     == output float dataset = abs(DFT)
 -nfft N  == use 'N' for DFT length (must be >= #time points)
 -detrend == least-squares remove linear drift before DFT
             [for more complex detrending, use 3dDetrend first]
 -taper f == taper 'f' fraction of data at ends (0 <= f <= 1).
             [Hamming 'raised cosine' taper of f/2 of the ]
             [data length at each end; default is no taper]
