Hello experts,
I am trying to correlate cortical surface area measure with behavioral measures using instructions from here: https://surfer.nmr.mgh. harvard.edu/fswiki/FsTutorial/GroupAnalysis
After I overlay pcc.mgh (partial correlations) and sig.mgh files on lh.inflated, I see some clusters with high PCC values (Destrieux atlas) (please see attached figure) at "unlabeled subcortical regions" for one of the behavioral measures, out of 4.
Although for volume and thickness versus any behavioral measures, I do not see any "unlabeled subcortical regions" clusters like this.
Could you please advise me if its normal to get these clusters? If so, how can I interpret that?
Or Am I doing something wrong during preprocessing? If so, any help to find out where I might be doing wrong and to fix the issue would be really appreciated.
Thanks.
