Hi KC

I think that not all regions occur in all subjects. I know that is true of Christophe’s parcellation and think it is also true of Ron and Rahul’s, but I’ll cc Ron who can comment

Cheers

Bruce

External Email - Use Caution

Dear all,

I had an understanding that Desikan-Killiiany atlas can parcellate total of 68 regions from both hemispheres. However, after running recon-all -all, I can see total of 62 regions. I am afraid if you could help me understanding these discrepancies..

Thank you for your help.

Regards,
