Hi everybody
I have resting state data, TR=2.5s, 3 runs of 210 points per subject. The lab I'm working for had a pipeline making use of 3dFourier to perform bandpass filtering in the range 0.01-0.1 Hz, making it in two steps, fist highpass then lowpass.
I was trying to improve the code, I saw that 3dBandpass improves the demenaing of data, now I have a couple of questions
- what's the difference in terms of implementation of the filter between 3dBandpass and 3dTproject, if I only need to filter data (no nuisance regression)?
- given that the order have at least to be reversed (fist lowpass then highpass), is there any actual advantage in splitting the bandpass filter in lowpass and highpass?
Thank you
Simone
