Afni3dFourier
Afni3dFourier is a wrapper for the AFNI (RW Cox, NIH) 3dFourier application.
3dFourier -- Program to do Fourier filtering of 3D+time datasets along the time axis.
AFNI 3dFourier was written by T. Ross and K. Heimerl, Medical College of Wisconsin.
For more information about the AFNI package, see the AFNI Homepage

Invocation
java Afni3dFourier
This starts up the java interpreter and runs the Afni3dFourier application.
You need to have set up your environment
for java in order for this to work.
Afni3dFourier window
- Input dataset
This is the input dataset to be filtered.
This program accepts datasets that are modified on input according
to the following schemes:
'r1+orig[3..5]'{sub-brick selector}
The sub-range selector <> and 3dcalc schemes are supported by the
command line program, but not in the GUI.
- Output prefix
Output name for the new 3d+time dataset to be generated (default fourier)
- Lowpass cutoff frequency (Hz)
Low pass filter with a cut-off off Hz.
- Highpass cutoff frequency (Hz)
High pass filer with a cutoff off Hz.
- Ignore specified no. of images
This option ignores the first n images (default = 1).
- Restore mean and linear trend after filtering
Any mean and trend are removed before filtering with this option.
Afterwards, the trends will be restored.
- Multiple Run Options
