Hi Tania

I believe (Benjamin can confirm) that the SynthSeg label outputs are the same as the aparc+aseg.mgz that recon-all creates. This is the combination of the whole brain segmentation labels in aseg.mgz with the parcellation labels in the aparc.annot file (the Desikan-Killiany atlas)

Cheers

Subject: [Freesurfer] Feature associations between recon-all and synthseg

        External Email - Use Caution        

Hello,

I am reaching out to seek guidance on associating brain features generated using SynthSeg (approximately 101 features for the whole brain) with those generated by Recon-All.

Given the coarse nature of SynthSeg features, I assume that multiple features from Recon-All might correspond to a single region in SynthSeg. For example, one Synthseg feature is: 

ctx-lh-caudalmiddlefrontal

How can I determine the set of features in recon-all that correspond to this region ctx-lh-caudalmiddlefrontal?

Thank you in advance for your time and assistance.

Thank you,

Tania Banerjee
