Dear all, I followed the procedure described here in order to do small volume correction (https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind1609&L=spm&P=R9957&1=spm&9=A&I=-3&J=on&X=B7BEC341E8A293F825&Y=ariadna.albajara%40gmail.com&d=No+Match%3BMatch%3BMatches&z=4)
and I would have a few questions:
(1) I selected the constrast, p value adjustment to control: “none”, threshold: “0.001”; extent threshold: 0.
(2) I defined my small volume.
(3) I looked at FWEp at the bottom up the results table. In my case FWEp: 4.963.
(4)I reloaded the contrast, p value adjustment to control: “none”, threshold: “4.963”; extent threshold: 0.
(5)I defined my small volume like in (2) and found that at the peak-level: Pfwe-corr=0.030.
Is this alright?
My questions are:
a) FWEp would be then different for each small volume. Is this okay?
b) How would you describe this procedure in the method section?
c) At the peak-level, Pfwe-corr=0.03. How should I report this result? “Small volume correction analysis revealed a significant activation pFWE= 0.03 OR pSVC= 0.03?”
Thank you in advance,
