I don't think so, but Rahul (ccd) would know for sure. I think a bunch of them cross lobar boundaries

Hi Bruce,

Are you saying that you don't think I even could build these lobar groups using the existing codes in the LUT.txt file?

Hi Lee,

sorry, not really - we've never done a lobar parcellation, and I don't think the existing units break down that way.

I know that I could go thru the FreeSurferColorLUT.txt file to get codes for different cortical structures. Is there an easier way to get the major lobes: frontal, parietal occipital and temporal.

The occipital lobe also includes the pericalcarine region (i think you just forgot to include that one in your list).

Hi Lee,

Bruce is correct in that some ROIs cross two or more lobar boundaries (i.e. fusiform) while others (i.e. cingulate subdivisions) can be considered separately or can be included to follow the 4 lobes. To the best of my ability, if you are using the *h.aparc.annot, you can add up the individual ROIs as such to get the lobes:

Frontal: Superior Frontal Rostral and Caudal Middle Frontal Pars Opercularis, Pars Triangularis, and Pars Orbitalis Lateral and Medial Orbitofrontal Precentral Paracentral Frontal Pole

Parietal: Superior Parietal Inferior Parietal Supramarginal Postcentral Precuneus

Temporal Superior, Middle, and Inferior Temporal Fusiform Transverse Temporal Entorhinal Temporal Pole Parahippocampal

Occipital: Lateral Occipital Lingual Cuneus

Cingulate (if want to include in a lobe): Rostral Anterior (Frontal) Caudal Anterior (Frontal) Posterior (Parietal) Isthmus (Parietal)

Best,

rahul
