Dear Jürgen,
if I remember correctly, the correction for non-isotropic smoothness is
implemented only in spm_list.m. This produces the table, but not the
glass brain. Hence, it is a feature to display the corrected values in
the results listing.
It would require some programming work to implement the same correction
for the glass brain, too.
