Dear Jihyun,

The boundaries overall look fine to me, except as you say on the mid-top slices where the boundaries seem to be missing, which is weird, and I have never seen that.

Can you please try to do the same check on the structural? Also is this on the average of functional connectivity of all subjects or only on one specific subject? If the latter, is the same "bug" happening on other subjects as well?

Hope this helps,
Stephen
