Hi Bruce,
Yes, this is patient population. I ran the following command after adding control points along the white surface:
recon-all -autorecon2 -autorecon3 -subjid <subj>
Thanks for the offer to try out reconstruction in the data. I have uploaded the dataset and allowed access by you and Khoa. Kindly let me know if I should include others.
Thanks and regards, Sindhuja
Hi Sindhuja
is this a patient population? It looks to me like there are lesions in the gray matter which will definitely mess up the pial surface deformation. We can try some things if you want to upload the data
cheers Bruce

Hi Bruce and Khoa,
I've attached the snapshots after adding control points and using autorecon2. So it looks like the control points extended the pial surface by a bit, but there is still some gray matter is left out.
The same was observed in some other dataset as well.
What command did you run? Do you want to upload the dataset?

Hi Khoa and Bruce,
I added control points along the white surface - it did not help much in extending the pial surface.
Looks like there might be some kind of gray matter pathology there as well

Hi,
How is the intensity of the wm between the putamen and the white surface? If it's lower than 110, you can place a string of control points along the inside border of the white surface. That might help extend the pial surf to include all the gm.
