Hi all,

I've just started to do cortical thickness analysis on some subjects and 
I'm noticing some miss-registrations, more specifically the Talairach 
image is smaller than the target image no matter what subject I look at! 
I just wanted to make sure if this is something normal and to what 
extend it's going to effect the individual cortical thickness 
calculations. I guess I'm not sure how the Talairach trasnformation is 
used in further steps of the cortical thickness calculation. I've 
attached example coronal, sagittal and horizontal slices of one of my 
subjects. I greatly appreciate your advice.

Thanks,
