Hi freesurfers,

  I am running into an error where the white matter and gray matter means
of my atlas are automatically setting to 0 during the #@# CA Normalize
pathway. I copied a code segment below to help explain better. Has anyone
else run into this problem? Is there a way to manually change these
averages?
