Hi Freesurferers
Could you please let me know how I should calculate the high pass filter cutoff? I have seen a bunch of different formulas (i.e 1.5*the stimulation period)? My task is a block-designed task, each stimuli takes 16 seconds and is followed by the next stimuli without an ITI. TR=2, number of conditions=8. I have used a hpf=0.01, Is this correct?
Thanks Mona
