RE: ALFF CONN Methods?
This is very helpful, Alfonso!
In the variance and mean terms of the preceding ALFF equations, what does the N denominator denote?
Also, I have seen papers that further restrict ALFF analyses to slow-5 (0.01-0.027 Hz) and slow-4 (0.027-0.073 Hz) bands. To do this on CONN, would this require processing the data as normal but restricting the the filter to these ranges? I already have my omnibus results for 0.01-0.09Hz. Anyway to use these data or must I redo the processing with the slow-5 and slow-4 ranges?
Warm regards,
Jeff
