Hi, I am new to FreeSurfer and even after having read the wiki, I have a few questions regarding the coordinate systems.
1. What coordinate system do the final surfaces have. ie. mris_convert rh.pial rh.pial.ascii will list the coordinates in what space?
2. Are the coordinates of T1.mgz and rh.pial for example the same, or does tkmedit compute transforms on the fly so that everything is aligned properly when you view it.
3. What transform (or combination of transforms) will get me from the final surfaces coordinates, to the MNI talairach like space (which I think is called avg305).
many thanks, mishkin
