Dear experts
I use the following command and the Size(mm^2) was28.65.
mri_surfcluster --in leg.volume.lh.20/g2v2/sig.mgh --thmin 3.7190 --no-adjust
--sign abs --subject fsaverage --hemi lh --annot aparc.a2009s --mask
leg.volume.lh.20/mask.mgh --sum leg.volume.lh.20/g2v2/sig.z3.7190.txt
# ClusterNo Max VtxMax Size(mm^2) TalX TalY TalZ NVtxs
Annot
1 4.068 160031 28.65 -7.5 -42.6
9.2 87 G_cingul-Post-ventral
However, When I used the FDR correction and found that size become larger
(76467.08).
mri_surfcluster --in leg.volume.lh.20/g2v2/sig.mgh --fdr 2.3 --no-adjust
--sign abs --subject fsaverage --hemi lh --annot aparc.a2009s --mask
leg.volume.lh.20/mask.mgh --cwsig 5 --sum fdr.2.3.txt
# ClusterNo Max VtxMax Size(mm^2) TalX TalY TalZ
NVtxs Annot
1 4.068 160031 76467.08 -7.5 -42.6 9.2 149953
G_cingul-Post-ventral
Why the size become larger ? Or is there some problem?
Thank you
