Hi Jeff, do you just want to map the annotations from fsaverage to your
individual subject? If so, you can use mri_surf2surf, something like
mri_surf2surf --srcsubject fsaverage --trgsubject yoursubject --hemi lh \
--sval-annot $SUBJECTS_DIR/fsaverage/label/lh.aparc.annot \
--tval $SUBJECTS_DIR/yoursubject/label/lh.subj1.aparc.annot
