[FieldTrip] What exactly does 'minnbchan' refer just to spatial neighbors?

It means ONLY spatial neighbors.

No, with minnbchan=0, there are no constraints on the clusters. If you want
clusters to be local (as opposed to stretched over a large part of the
scalp), minnbchan should be given a high value.
