Dear SPM experts,
i have a question regarding the high-pass filter in SPM 8.
i have following block design:
F A F B F C F D F E
F: fixation cross (5 seconds), A: block existing of 10 stimuli, each shown for 3 secs. B: block existing of 10 stimuli, each shown for 3 secs and so on. Every block represents a different stimuli category (e.g. A = happy, B = sad, C = neutral etc.) and is shown twice in randomized order. For example: F A F B F C F D F E - F B F C F D F A F E
Would it be appropriate to set the cut off for 350 secs?
