It is a defect of some kind. Use the save point / goto feature of tksurfer and tkmedit, as described in the tutorial, to see discover the cause of the defect. That is, click on a point on that needle in tksurfer, click save point, then click goto point in tkmedit, after loading the brainmask and whitematter surfaces. Probably some dura is remaining.

Hi I have run the recon-all -autorecon2 command and I checked the inflate surface, it seems like something like a needle on the surface, Is this normal? I paste some pictures in the accessory, and by the way, I checked the white matter surface and pial surface and they seems all right.Can somebody tell why there is a needle on the surface? Thanks in advance.
