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

External Email - Use CautionHi,
I transfered the SPM Anatomy Toolbox (http://www.fz-juelich.de/inm/inm-1/DE/Forschung/_docs/SPMAnatomyToolbox/SPMA...) 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. (mris_ca_label.png)
How can a keep unassigned regions unlabeled?
