[Freesurfer] seed point on the CC and Pons

External Email - Use Caution

Hello Freesurfer Experts

I am trying to set the correct seed point to cutting the corpus callosum and pons for a macaque subject. It is aimed to remove the brainstem and cerebellum, right?

My command line is :

recon-all -s monkey2 -autorecon2-inflate1 -noaseg -cc-crs 100 85 112 -pons-crs 99 105 80

The output result is sucessed without errors, but the wm.mgz still include the brainstem and cerebellum in my freeview. I am wondering whether my coordinate used above command is correct ? It is from the Cursor on the right of wm in attached pictures. I know here need talairach coordinate and which one on the Cursor is correct ?Sorry for my ignorance. Any suggestions will be appreciated!

Kind Regards

Jie
