Hi John
sorry, not really. If you constrain the topology of the cerebellum you will
probably loose a lot of it since the folia are so small. You can try using
Florent Segonne's old code (mri_topologycorrection), which will generate a
discrete segmentation that has the correct topology (hopefully!), but I
don't believe that guarantees that covering the surface of it will also be
topologically correct.

Hi Dr Bruce,
I applied your recommendations and I was able to create surfaces to the
cerebellum and brain stem using the command mri_tesselate. I am not happy with
the topology though... There are holes and some defects. Would you recommend
any commands to improve the topology of these structures?
Your guidance is appreciated,
John

Hi John
we distribute an aseg.mgs with fsaverage I believe. You can just
tesselate that.

Hi Dr Bruce, I highly appreciate your guidance.
I would like to load the cerebellum and brain stem structures as an average
structure similar to
"fsaverage" , I usually use the command
tksurferfv fsaverage lh pial -overlay <image>
mri_tessellate or mri_mc would create a surface for every subject, how can I
create the average of the
surfaces of those structures similar to "fsaverage"?
Thanks again for any highlights
John
Hi John
you could use mri_tessellate or mri_mc to create a surface for those
structures, then smooth them with
mris_smooth and load them into freeview.
Shouldn't be too hard.
cheers

Dear FS experts,
For visualization purposes, is there any way to show the cerebellum and brain
stem regions
(similar to the attached figure), this figure was published used CONN toolbox
but I am not sure
how they were able to map functional data in brain surface and show the
cerebellum and brain
stem with fsaverage.
I appreciate any suggestion
Jon
