Hi,
I would like to apply the wang atlas over the group activation maps
produced from Freesurfer analysis. I would appreciate any
guidance/instructions you can
That does not look like it is a problem with the input image. Do you
have a normal, invivo MRI that you can run samseg on to see if it is
just a problem with your platform?

Dear FS community
I have an ex-vivo human
The way I have done this was do compute T1w images (MPRAGE) through
simulations, then run recon-all on that.

Dear FS community,
Recently our lab started collecting 3D-QALAS (Cho et al., 2023). Using
this
if this would require a voxel wise analysis or
an ROI analysis… to my understanding this is more of a ROI analysis
between subjects - is this assumption incorrect?
Thank you,

I would also be helpful to have some pics of what you are seeing. The
surface is not valid in the "medial well" -- ie all the non-cortical
structures on the central sagittial plane such as thalamus an VDC.

I don't understand. Why not use the mean thickness from FS? We have an

Sorry I should have clarified. Yes, I would like to perform voxelwise
analysis of FA and MD values of hippocampal subfield between subjects.
Is this possible with free surfer?
Thank you again for your time.

Hi there,
Is there a way to successfully obtain FA/MD values from the
hippocampus subfields?
Thank you,

I suspect the problem is with the aseg.mgz input. You can regenerate
that with the new surfs with a different call to mri_surf2volseg.
However, that will take a --fix-presurf-with-ribbon argument, so you
will also have to regenerate the ribbon.mgz file for the new surfaces
with mris_volmask
You can try using mri_synthseg --i orig.mgz --o synthseg.mgz
it generally does a better job on cerebellum than the native FS command

I don't understand. Why not use the mean thickness from FS? We have an
