What do you mean by the interaction contrast? Or do you mean the
intercept? It is not surprising that the intercept is completely yellow
as that is just testing whether the mean thickness is different than 0,
which it always will be.

However, the uncorrected significance map for the interaction contrast
is turning completely yellow, for both hemispheres.
After correcting for multiple comparisons, the result is a whole-brain
cluster, for both hemispheres too.
The pcc.mgh map is also fully painted.
But the maps for the slope contrast are correct.
I am sending the fsgd file, the matrix files, the commands that I run
and what appears on the command screen after running the commands to
open the significance and pcc.mgh maps in freeview. (I'm not sending
example images because my email has already been denied for being too
big).
Was this supposed to happen?
Thanks in advance!
