For images containing a single volume, there is space in the NIfTI headers for
the information about the orientation of the images. This information used
to be in the .mat files. However, if you have 4D data, then an additional
.mat file is still needed.
For more information, see http://nifti.nimh.nih.gov/nifti-1
