External Email - Use Caution I think one way to do this would be to split the atlas into a set of label files using `mri_annotation2label`. I would do it for the fsaverage subject. This will give you one label file per atlas region. Something like this:
cd /path/to/freesurfer/subjects/ mri_annotation2label --subject fsaverage --hemi lh --outdir fsaverage/label/aparc_labels --annotation aparc # repeat for rh Then you could first load the fsaverage surfaces (e.g., lh.white and rh.white) into freeview, and then add only the labels of the regions you want to show. Maybe someone else knows an easier way?
