Hi Martin
at the end of recon-all we correct the volume-based segmentations with
the surfaces, so the aparc*.mgz files should be pretty accurate

Here's the exact code that I used:
surface:
mri_label2vol --annot aparc.a2009s.annot --regheader $1/$2/mri/orig.mgz --o
$1/$2/roi/mask_lh.nii --temp $1/$2/mri/orig.mgz --subject $2 --hemi lh
--proj frac 0 1 .1
same for the right hemisphere.
volumetric:
mri_label2vol --seg
I would just use the 2nd command since aparc.a2009s+aseg.mgz will have
already resolved the issues of overlap that you mention.

Hi Doug,
Thanks a lot. But aren't the aparc.a2009s+aseg.mgz the volume-based ROIs
and aren't they less accurate than the surface-based ones?
Best,
Martin

Ok, I think now I see the misunderstanding. I thought Freesurfer creates
both volume-based *cortical* ROIs and in a later step surface-based
cortical ROIs, but if I get it right the aparc is already based on the
surface. Do I understand this correctly?
Best,

How did you create the ROIs?

I have spent quite some time on the wiki and searching through the emails
before writing to the list, but I might have missed some important
information.
I would like to work on anatomical ROIs
