Import new freesurfer volume atlas in subject space for SEEG electrode localization

Thank you! I imported the atlas and created the surface successfully. And I want to show the SEEG contacts with functional data (amplitude of sEEG or so) in the new thalamus surface, but I find the new surface cannot be shown during displaying the SEEG contacts or sEEG data. So I wonder what was the problem?

Thank you for your help!
