Hi Dr. Kamphuis,
The coordinates in the ID window reflect the coordinate space of the
primary fiducial surface that is currently loaded. Are you using one of
our atlases (e.g., the colin atlas)? If so, this atlas is available in
four spaces (711-2B, AFNI, SPM2, and SPM99). So if you have the SPM2
fiducial coordinate file loaded, then your coordinates are in avg152T1
space (the atlas target used for warping the surface coordinates).
These coordinates should be consistent (i.e., be in the same space) as
the corresponding left and right cerebral hemisphere fiducial surfaces
for Colin in SPM2 space.
If you're not using colin, but rather some other cerebellar surface,
then I will need more information to understand the relationship between
the cerebellar and cerebral coordinate spaces.

Hello,
Is there a possibility to convert to coordinates given in the Identify
Window (Main Window Fiducial XYZ) of a Cerebellum surface to the
coordinates given in the Identify Window of a Cerebral surface? As far
as I understand are the latter TAL coordinates, but I don't understand
the coordinates given in the ID Window of a Cerebellum surface.
Thanks a lot!
