Dear Freesurfer experts,
I am processing some atrophic brains with Freesurfer. However considerable part of 2 participants' brains (WM+GM) is not recognized (especially for participant B, the posterior part is not processed at all). I have checked the Talairach registration of both, only the borderlines of the posterior brain regions are not exactly accurate. Then I have tried to add thousands of control points and run the <recon-all -autorecon2-cp -s subject name> but that doesn't help.
Please find the attached slides of 2 participants. Could you please give me some suggestions for better processing or further editing? Many thanks!!
Kind regards, Zixuan
