SnPMt.mat does not save non-brain voxels, and that is why the data
matrix size is considerably smaller than the original image size. This
saves some disk space too!
As for translating the results into image coordinates, under the same
directory, there is a file called XYZ.mat, which contains the x-y-z
coordinates (in world space) of all the voxels in SnPMt.mat.
Good luck!
