[Freesurfer] detecting movement artifact

Hello, freesurfer experts

We are doing the structure scan on the adolescents. One potential problem is the head movement from the participants. But so far from the image, it looks ok.

The question is

1 What is the visual check after autorecon3? We did the visual check after autorecon1 and autorecon2 to examine the skull stripping and pial/white surface.

2 Even freefurfer finished without error after all the recon-all steps, does it mean the data is of good quality. Is there any way in freesurfer to do a quality assessment of the image?

Thanks a lot! _________________________________________________________________ Live Search视频搜索，快速检索视频的利器！ http://www.live.com/?scope=video
