External Email - Use Caution        

Dear Freesurfer Developers,

I hope this email finds you all safe and well. I have two questions regarding the new version of freesurfer: 

• Is there a new CLUT associated with FS7? I tried to use the CLUT labels to extract thalamic subnuclei ROIs, but got empty ROI files.

• Given that Freesurfer version 7 contains segmentations not previously generated in recon-all (i.e. hippocampal subfields), is it possible to extract these ROIs using aparc+aseg images generated using previous versions of Freesurfer? Or do we need to repeat the cortical parcellations (i.e. rerun recon-all) using FS7? 

I’d highly appreciate your time and feedback on this matter. Thank you.

Best,

Ameen
