Hi,
In task-type fmri image processing, I’d like to apply a bandpass filter [0.01Hz, 0.1Hz].
I’m wondering how to implement this process.
Should I use fft and band pass it and ifft to get the real part?
Or I should use the zero-phase forward and reverse digital IIR filtering like filtfilt in matlab?
Is there a theoretical support about this?
Thanks !
