-ny n2        n2 = number of voxels along y-axis                      
-nz n3        n3 = number of voxels along z-axis                      
-dx d1        d1 = voxel size (mm) along x-axis                       
-dy d2        d2 = voxel size (mm) along y-axis                       
-dz d3        d3 = voxel size (mm) along z-axis                       
[-mask mset]      Use the 0 sub-brick of dataset 'mset' as a mask     
                    to indicate which voxels to analyze (a sub-brick  
                    selector is allowed)  [default = use all voxels]  
                  Note:  The -mask command REPLACES the -nx, -ny, -nz,
                         -dx, -dy, and -dz commands.
