Set up - MNI Boundaries
Hi,
I am currently going through QAs.
It seems like I am getting imperfect MNI boundaries (picture attached)
This boundary is not covering the whole brain in mid-top region.
I am wondering whether this may lead to the inaccurate result.
Also, the boundary is looking much better when I display raw data instead of smoother display.
Any tips of solving this would much appreciated
Thank you

RE: Set up - MNI Boundaries
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

The MNI boundaries on structural look same as the one on functional.
When I look at the single slice level, the boundaries seem to be present but very sparse and not solid thick yellow line.
Will this impact the analysis?
