Thanks Bruce and Brian, When voxel dimensions are less than 1.75, "create surface" went smoothly.
Question: The pons is still attached, I want to use -pons-xyz X Y Z TkMedit shows only RAS. (1) How can I have talairach coords shown up on TkMedit (2) RAS and Talairach coords are different, but the manual says use either one. it doesn't matter? Thanks for you answer.
