Dear SPM Experts,
maybe this has been discussed before.
We just found, that the activated area is much larger with the same
statistic on normalized data than in the same data without normalization.
Smoothing (8*8*8) has been performed in both cases as the last step before
the statistic.
Could it be, that the normalization step introduces further smoothing and
if so, how can I determine the resulting smoothing kernel.
Thanks in advance,
Peter
