Hi, can someone tell me in user-friendly steps how to determine a low pass filter cutoff value, in general, and for my specific study ? (i.e. i want to remove any high frequency noise using the 3dFourier tool)
TR = 2.4 s
Block design
12 sec off/ 12 sec on
5 block types, each repeated once per scan
Sample Scan (240 s total):
blank-cndA-blank-cndB-blank-cndC-blank-cndD-blank-cndE-blank-cndA-blank-cndB-blank-cndC-blank-cndD-blank-cndE
Thanks!!
Mark
