To make it clear, I would like to extract the area of each subject in the cluster. May I know if this is the correct way? If not, it’s appreciated if you would point it out. Thanks!

Dear Freesurfer Experts,

As I’d like to extract the average value of each subject in the cluster after running group analysis, may I know the unit of these numbers?

Since the one I’m running is surface area, and the cluster is 444mm^2, all the numbers in the file cache.th40.neg.y.ocn.dat is in the range of [0.55 1.05], may I know if this is correct and if so, how the unit is for those? Thanks a lot!

ClusterNo	Max	VtxMax	Size(mm^2)	MNIX	MNIY	MNIZ	CWP	CWPLow	CWPHi	NVtxs	WghtVtx
1	-4.8321	40067	444.11	-58.1	-16.6	-23.9	0.0002	0	0.0004	670	-2784.11

Regards,

Xiaoxu
