Hi Charles,
The new cortical/cerebellar/striatum parcellations are derived from the resting-state fMRI data averaged across 1000 subjects in MNI152 space.
If your subjects have already been warped to MNI152 space, then you can simply use those parcellations (which are in the $FREESURFER_HOME/average/ directory). Alternatively, you could warp the MNI152 parcellations to your subjects' native structural MRI space.
I am not sure if Bruce has a better solution since he says "we are working on something" in this email to you.
Regards, Thomas

Dear Freesurfers,
I would like to perform cerebellar parcellation on structural mri with freesurfer. I asked if this was possible 6 months ago (see message below, saying that this feature wasn't available for now). I checked on freesurfer wiki the release notes about Freesurfer version 5.2.0 saying that new cortical parcellations and label were available.
"Cortical, Cerebellar, Striatum Parcellation in MNI152 space found in average/<Yeo_JNeurophysiol11_MNI152>, average/<Buckner_JNeurophysiol11_MNI152> and average/<Choi_JNeurophysiol12_MNI152>. See README file in each directory for more details. Note that these README files will be updated to reflect minor improvements in parcellations beyond the publication wikipages".
My understanding is that cerebellar parcellation on structural mri is still not available, could you tell me if I'm right ? When I'm checking the link on the release notes it doesn't seems to concern structural imaging.
Thanks a lot for your attention, sorry if my question seems obvious but I'm not very familiar with freesurfer.
Charles
PS : -answer : Hi Charles, that is true at the moment, although we are working on something that should be ready relatively soon.
cheers Bruce
-question : Dear freesurfer, I'm trying to perform parcellation on the cerebellum. After reading closely freesurfer wiki and the questions related to this topic on the mailing list, my understanding is that there is no way to perform fully automted cerebellar parcellation on structural mri with freesurfer. Could you tell me if I'm right ?
Thanks a lot for your attention
Charles
