Hi all:
I am confused with coordinate systems in FS. I have several questions
bellow.
1. when we run recon-all -s subjid -all, Is the individual native space
transformed to talairach coordinate system?. when run recon-all -s subjid
-qcache, does the talairach system go into MNI system (fsaverage space)?
2. what is the tranformation matrix within the file of
<subjid>/mri/transforms/talairach.xfm?, what is it used for?
3. Does the coordinates within .label files under <subjid>/label/ belong
to the MNI coordinate system?
4. In TkSurfer Tool, does the coordinate of "Vertex RAS" belong to MNI
coordinate?
Hope someone gives me suggestions.
best
