Dear SPM users,
I need your help urgently, after failing to find an answer to a somewhat
intriguing problem.
I recently started to do group averaging in SPM and normalized all
the brains to a template in SPM (default). The statistical results
look good and have nice time course. However, when I check the
coordinate of the center of my ROI in the Talairach brain map, I
found that the particular position is outside the talairach brain,
at a blank, no tissue position.
Could you tell me why this is happening? Is SPM really using the
talairarch system to do normalization? If not, how interpretable
are the coordinates given by the statistical results?
Your help is greatly appreciated.
Yuhong
