Re: [Freesurfer] temporal lobe left out in pial surface - edits on brainmask.mgz or brain.finalsurfs.mgz?
Hi Michael,
This method seems cool. I'll try to implement it. Thank you so much.
Best, Cherry

Ok. I'll give it a try. Thanks, Chris & Bruce!

Hi Cherry
Chris is right. Putting control points in the WM will help the pial surface as well.
cheers Bruce

Hi Chris,
Thanks a lot. I agree that control points should actually only be put in white matter. I'm just not sure if I can expand the pial surface to a satisfactory extend if I only do edits in the white matter. It seems to me that the problem here is that the signal weakened in the lower part of the brain so that the gray matter doesn't have adequate intensity to be included in the pial surface (the values are around 30).
Thanks, Cherry

Hi all,
This is a follow-up on my question so that people can know what I've tried and how it works. I added control points in the white matter and the delineation of the temporal lobe has improved to a satisfying level. We also find what Michael has suggested very interesting. But it seems that if we change the parameters for certain subjects, we would have to rerun all of the other subjects with the same set of parameters, which may not be desirable at the moment.
Thanks for all the help, Cherry
