it doesn't really matter. We frequently erase it as (1) it's non-cortical, and (2) it ends up being a little strand on the inflated surface. It won't matter if you leave it though

Dear Martin,
Thank you so much for your reply.
I searched the freesurfer mailing list, and indeed it seemed that

axons, which automatically qualifies as "white matter". Is this a
contradiction?
Thank you!
Sincerely,
Ye
