In Glasser360 Atlas, where in the brain is ROI 103 and which network is it assigned to?

I think it’s called Right_52. I’m tried opening the glasser360MNI.nii.gz file in fsl and mricron but that wasn’t much help.

Thank you!

That index gives L_area_52 in the Glasser atlas distributed with AFNI. Right and left for the labels was likely given a different offset in the version you are using. This should be Brodmann area 52. It looks like this in the afni GUI with the Glasser atlas selected to atlas colors.
