RE: Regarding group-level matrix thresholding
Hi Corinna
If a connection is 0 for all subjects, then the NBS will automatically ignore that connection during statistical testing.
In other words, if the connectivity value for a given connection is zero in all connectivity matrices, that specific connection is ignored by default and the number of multiple comparisons reduced accordingly.
