Hi Wayne, this is the problem with these types of corrections. As you
change the parameters, the null distribution for cluster sizes change.
At a threshold of .01 you may get a cluster that is smaller than at .05,
but it may be more significant because the shape of the null
distribution change
Dear Freesurfers,
I used Qdec to do two-group comparison on cortical thickness. Demeaned age
was used as the covariate. The question I¹m looking at is that ³Does the
thickness-age correlation differ between C1 and C3?²
When FWHM=15mm was chosen, I got confused results: When I used threshold
