Hi everyone,
I've gone through the listserv, and it's still not clear to me how to properly bandpass filter data using fslmaths.
My TR is 2.0 seconds.
I want a Bandpass filter of 0.01 -0.08 Hz.
Therefore, 0.01 Hz=100 seconds, and thus, 50 volumes. But what is the sigma?
Similarly, 0.08 Hz=12.5 seconds, and thus 6.25 volumes. But what, again, is the sigma?
Any help is appreciated.
Massih
