Hello, Martin

Yes, the longitudinal brainmask I meant is the brainmask.mgz in the longitudinal dir, not from the base template.

Thanks!

Hi Guang,

what do you mean with 'longitudinal brainmask'?
You need to overlay the segmentation to the brainmask in the longitudinal subject dir. The brainmask in the base dir is in a different space.

Hi, there,

I ran the freesurfer longitudinal stream to analysis scans from two tps.
I attached the segmentation results of one time-point to its orig.mgz and the longitudinal brainmask,
I can see part of the brainmask are not labeled, I understood that it is because  of the brainmask is the mean or median of
the norm.mgz from different time points. Just wanna double check that the results is ok.

Thanks!
Guang
