Hi,
I'm performing MVB on various regions of interest and can't help feeling that the size of the search volume one selects will impact quite drastically on the log evidence for a particular spatial prior. Is there any rule of thumb for determining the ideal search volume given the size of the ROI?
And on top of this, is there anywhere in which the four different spatial priors are expained in Layman's terms?
Thanks,
Paddy
