Masking per se will not implement a restriction of the search volume
(it simply allows you to select a subset of voxels). To effect a
constrained search you have to explciitly perform a small volume
correction using the cluster defined by a mask. Simply select SVC and
then the cluster option and the table will change to give you corrected
p values for that cluster.
I hope this helps - Karl
