Dear SPMers,
I've calculated a volume with corrected p-values in Matlab (not SPM) for
my fMRI dataset (3.75 mm voxels). Now I want to interpolate these
p-values to show them on a T1 volume (1 mm voxels), how should I do the
interpolation? I can't use ordinary interpolation since an area of a
slice can look something like this
1.00 0.80 1.00 1.00 1.00
1.00 0.70 0.80 1.00 1.00
1.00 0.01 0.02 0.03 1.00
1.00 0.08 0.05 1.00 1.00
and the interpolated p-values with ordinary interpolation then become
very wrong. How is this handled in SPM?
I know that p-values normally not are visualized, but I want to compare
two different statistical approaches and their test values are quite
diffucult to compare.
/Anders
