Hello freesurfer Expert,
Steps for measuring cortical thickness are in tkmedit :
  1. Intensity normalisation,

  2. Registration to Talairach space,

  3. Skull stripping,

  4. Segmentation of white matter,

  5. Tesselation of the WM boundary,

  6. Smoothing of the tesselated surface and automatic topology correction

Can u help me to step no 5 and 6. How to do this steps.

Thanks,
