you can generate them with

cd $FREESURFER_HOME/subjects/fsaverage/surf

mris_left_right_register lh.sphere rh.sphere lh.sphere.left_right rh.sphere.left_right

should take less than an hour to run

        hemispheres

If you have a label defined on the lh or rh of fsaverage, you can
map it
to the contralateral hemi with something like

mris_apply_reg --src-label lh.your.label --streg lh.sphere.left_right
rh.sphere.left_right --trg rh.your.label

where the left_right files are in fsaverage/surf

My fsaverage doesn't seem to have those registrations (we're still on 5.3) - I have lh.sphere, lh.sphere.reg, and lh.sphere.reg.avg but nothing with the .left_right suffix.
