L and R masks not symmetric
Hello,
I created a few masks using wfu_pickatlas ver 3.0.5 and noted that the L and R masks are not symmetric. I have noted this before in previous versions as well but have never seen a discussion as to why that may be. See attached for a few examples.
Any ideas as to why this may be?
Thanks,
Keith

Hi Keith,
I am unable to find the area (OFC) you mention in the image. How did you define it?

Hi Keith,
The simple answer to the questions is this is an example of asymmetry in the original AAL atlas. It may help to review the methods of the original atlas generation: http://www.cyceron.fr/index.php/en/plateforme-en/freeware.
