Hi Freesurfers,
Happy Holidays! I have a subject failing at Intensity Normalization, and upon checking the talairach, I found that it is very bad. When loaded in tkregister2, the talairach is off the screen, and the orientation is off--coronal is matched to saggital).
According to the wiki instructions, I will need to correct the transform. Is it possible to fix this bad talairach in tkregister2?
If it is helpful, I have the error message from the Intensity Normalization error printed below.
Thank you! Caroline
