Usage: 3dFourier [options] dataset
-prefix name output name for new 3d+time dataset [default = fourier]
-lowpass f low pass filter with a cutoff of f Hz
-highpass f high pass filter with a cutoff of f Hz
-ignore n ignore the first n images [default = 1]
- -retrend Any mean and linear trend are removed before filtering.
- This will restore the trend after filtering.
Note that by combining the lowpass and highpass options, one can construct bandpass and notch filters
This program accepts datasets that are modified on input according to the following schemes:
‘r1+orig[3..5]’ {sub-brick selector} ‘r1+orig<100..200>’ {sub-range selector} ‘r1+orig[3..5]<100..200>’ {both selectors} ‘3dcalc( -a r1+orig -b r2+orig -expr 0.5*(a+b) )’ {calculation}
For the gruesome details, see the output of ‘afni -help’.
