Are you asking if that is a topological defect? It is impossible to say from one slice. The surface itself is ok to be there as that is on the medial well.

External Email - Use Caution

Hi

My name is Halil Ibrahim akçay. I am a neurologist.

I have been used FreeSurfer for a while. And I cannot understand some part of troubleshooting process. I am sending a screenshot of my question. How can I understand whether gray zone as marked blue circle is a problem or not in this picture? And Should I fill this zone to fix the problem, if this is a problem?

Thanx for your helping.

I am looking forward to your answer.

Best regards
