External Email - Use Caution
Hi experts,
I have extracted the area of the significant cluster with the command like the following: mri_segstats --i mgh/lh.volume.all.mgh --seg glmdir_az_vz/lh.volume.all.glmdir/av-group2-vs-group2/cache.th20.neg.sig.ocn.mgh --id 1 --sumwf group1_group2_volume_l.sum-clusters.dat
When I use a t-test for these two group summarized area value, the p value is 0.1398. I did the same process for other significant clusters. However, it is the only one without significant p-value. The detail of the cluster information is listed below.
# ClusterNo Max VtxMax Size(mm^2) MNIX MNIY MNIZ CWP CWPLow CWPHi NVtxs WghtVtx Annot

Could you give me some ideas where I should find the reason? Thanks a lot!
