Just to be clear, $FREESURFER_HOME/average/mni152.register.dat seems to contain a 4x4 matrix (M). So, if my RAS coordinates are (x,y,z), I would do the following:
M*[x y z 1]'
where the coordinates are stacked as a column vector? Or do I multiply on the left?
Thanks.

Hi Freesurfer experts,
I have a set of RAS coordinates in the Freesurfer fsaverage space. What is
the easiest way to transform them to MNI152 space?
Thanks.
