Hi,

I have a question regarding lobe (temporal, frontal, parietal, and occipital) segmentation. I have already completed a recon-all for all subjects. I have seen that the surface stream has a -lobesStrict function which parcellates the lobes. I have also seen that you can convert the surface to a volume through mri_surf2vol. This, I believe, would in the end get me what I'm after; which are the lobe segmentations. 

My plan is to overlay a lesion mask and extract the lesions based on, among other things, which lobe they belong to.

I was wondering if there was a way to use the segmentation outputs from FreeSurfer to get lobe segmentation directly, i.e. by adding up various segmentation volumes? Or do I have to go through the Surface stream?

Is my above-stated method the easiest and best way to get lobe segmentations in order to extract the lesion load per lobe?

Thank you for your time and help!

Best,

Michael
