            If a searchlight region does not have more than this minimum
            proportion of active voxels in the mask, it is not processed by the
            searchlight function. The mask used for the test is the
            intersection of the global (brain) mask and the `Shape` mask. The
            seed (central) voxel of the searchlight region is taken into
            consideration.
