Hi Qian

I'm not sure I understand what you think is wrong in the images you included. The first two locations look quite accurate to me, and I'm not positive but I think the third image the locations you circle are amygdala, so not neocortical at all

cheers

Dear Prof.Douglas Greve,
 Thanks for your reply. I add parts of problem screenshot of white/pial
surface. 

  When I did freesurfer for structure analysis, I was confused by some steps
and results. The analysis stream was:

1st: check data orientation

2nd : convert nii.gz  to mgz

3rd: recon-all –all –subjid sub01

After these steps finished , I checked skullstrip, segmentation quality. The
problems as following:

1st: skullstrip result not very well, almost need manually operation.

     After manually operation, I run:

 recon-all –autorecon2 –autorecon3 –subjid sub01

2nd: parts of white surface and pial surface not very exactly. I only did
adding control points to modify white surface, then I run:

       Recon-all –autorecon2-cp –autorecon3 –subjid sub01 brainmask.mgz

Several parts of pial surface exit errors. I added these as screenshot:

So when I met such issues, I should add control points for pial surface  as
white surface did (or how I correct or edit pial; still use tkmedit tool?) ?
Then I run: 

recon-all –autorecon2-pial  –autorecon3 sub01 ?

If white surface and pial surface all needed manually operated, whether I
could do like this: I add control points (-cp), edit wm (-wm), correct pial
(-pial ) at the same time, then I run:

recon-all –autorecon2-cp –autorecon2-wm –autorecon2-pail –autorecon3 sub01
or recon-all -autorecon2-cp brainmask.mgz -autorecon2-wm -autorecon2-pial
-autorecon3 sub01?

or any other suggestions?

Thanks very much!
Best Regards,
Qian Ran

      Hi Qian, things will be a lot easier if you imbed your comments
      and images in the email. From the text, I can't tell what you
      want exactly. The first question had to do with skull stripping.
      It looks like you had to make a manual edit. This is expected
      sometimes.  If it is more than that, what is the problem. In the
      second question, you had some problem with the quality of the
      white/pial surfaces, but there was not much detail or a picture.

      Hello Freesurfer Developers,
I have had last September Freesurfer course. When I operated my

step. Because I need put some screenshout to exaplain that
problems, I add word document in attachment. Thanks very much!
