Hello Freesurfer Developers,
I want to add vertecies to the cortex label as certain vertecies in the occipital lobe is wrongfully segmented as medial wall. Is there a way to do this?
Thank you in advance!
Cheers, Linn
Hi Linn
sure, you can edit the label directly. This might not be supported yet in freeview (Ruopeng: is it?) in which case you have to use tksurfer.
The other (and probably better) alternative is to figure out why the label is incorrect and edit the underlying cause. In the occipital lobe this is usually because the occipital horn of the ventricle incorrectly extends into the calcarine. You can fix this by editing the aseg to relabel those voxels as unknown and rerunning recon-all from their forward.

No, it is not supported in freeview yet.
