Hi Joerg
I'm not positive that I understand, but have you tried giving
mris_ca_label the switch:
mris_ca_label -l $SUBJECTS_DIR/$subject/label/$hemi.cortex.label ...
that should remove non-cortical regions from your output annot
cheers

Hi,
I transfered the SPM Anatomy Toolbox
(http://www.fz-juelich.de/inm/inm-1/DE/Forschung/_docs/SPMAnatomyToolbox/SPMAnatomyToolbox_node.html)
from Collin space to fsaverage using
Wu J, Ngo GH, Greve DN, Li J, He T, Fischl B, Eickhoff SB, Yeo BTT.
*Accurate nonlinear mapping between MNI volumetric and FreeSurfer
surface coordinate systems*
<http://people.csail.mit.edu/ythomas/publications/2018VolSurfMapping-HBM.pdf>,
/Human Brain Mapping/ 39:3793–3808, 2018.
mris_seg2annot --seg rh_Anatomy_v22c.nii.gz --ctab-auto Anatomy_v22c --s
fsaverage --hemi rh --o rh.anat_v22c
mris_seg2annot --seg lh_Anatomy_v22c.nii.gz --ctab-auto Anatomy_v22c --s
fsaverage --hemi lh --o lh.anat_v22c
This gave me the annot files for fsaverage (annotation.png) and a
template for the color lookup table.
Training of the classifier:
mris_ca_train -t Anatomy_v22c_LUT.txt lh lh.sphere.reg anat_v22c.annot
fsaverage lh.Anatomy_v22c.gcs
mris_ca_train -t Anatomy_v22c_LUT.txt rh rh.sphere.reg anat_v22c.annot
fsaverage rh.Anatomy_v22c.gcs
Transfer to individual subject fsaverage:
mris_ca_label fs_average lh sphere.reg lh.Anatomy_v22c.gcs
Anatomy_v22c.annot
mris_ca_label fs_average rh sphere.reg rh.Anatomy_v22c.gcs
Anatomy_v22c.annot
Now the miracle occurred and the whole surface got labeled.

How can a keep unassigned regions unlabeled?
