External Email - Use Caution
Hi,
I’m writing to ask about cortical parcellation (Desikan-Killiany and Destrieux), which do not work well on my recent anatomical scan (a new anatomical scan sequence that gives better grey and white matter contrast). I’m writing to ask if you know what is causing this artifact (ROIs are not covering all gray matter in depth direction) and from which step should I start to debug. Thank you for your help.
Best regards,
Yixin Ma

Hi Yixin
check to see if the lh.pial and rh.pial surfaces are accurate.
