Dear Friends:
I have a basic question and any help are appreciated.
SPM2 offers three choices for correction for multiple comparisons of
voxel-wise analysis, i.e., FWE, FDR, and none. Assume I chose none and
enter p and extent threshold. Now I get contrast result image. I click
on volume button to display statistics table. There is column named
Pcorrected at the left side of the table. Is FWE used to calculate the
corrected p value at cluster level?
Best Regards
Jiansong
