Dear Experts,
From my understanding, the segmentation of lesions within the brain tissue is none of your main interests. However earlier threads indicated that there are some tools related to FreeSurfer which could help with such a task.
Precisely, I am looking for a way to segment the surface of a lesion in a T1 dataset. I am not afraid of doing the segmentation manually (only 2 participants), but I would prefer receiving an output in FreeSurfer surface format which is coregistered with the regular output, e.g. lh.white, rh.pial, etc. Can you point me to a procedure within FreeSurfer or to a tool associated to FreeSurfer, to fulfill this task?
Any hint is appreciated very much. Thanks a lot in advance.
Best regards, Alexander Hunold
Hi Alexander
we do segment damaged white matter, although it's more accurate if you have a T2 or FLAIR. Check the aseg labels if you have run recon-all
