Hi FreeSurfer Developers,

 

I’m conducting manual ROI labelling on each participant’s inflated surface (after going through the ‘recon-all’ command), but I wasn’t very sure if the coordinates in the corresponding .label files are in MNI 305 space. At the top of the plain text files it’s showing ‘vox2ras=TkReg’.

 

If they are not in MNI 305, could you please explain a bit about what coordinate system is used here and how I could convert that into MNI 305?

 

Thank you very much!

 

Best wishes,

Vivian
