Dear SPMers,
I have a question on the high-pass filter.
In one of my tasks, I use a randomised event-related design with stimuli
type A,B, and C, each type 1/3.
SOAmin is 5-6 s (with random jitter).
The results with default high-pass filter (128) look a liitle noisy, and
I just wonder whether I can use a more strict cut-off, say 60.
In addition, a more general question is how the cut-off should be
decided in this case?
Thanks in advance.
Best,
Qing
