Dear SPMers,
When focusing in on a small region of the brain, as one does with a
small volume correction, what threshold is an accepted standard for
the SPM (in a standard t-contrast)? That is, should I threshold the
whole map at 0.001 uncorrected, then focus in on my ROI w/ an SVC, or
do I threshold the whole map at an even lower uncorrected threshold
(eg 0.01), followed up by an SVC?
Thanks,
Michael
