[Freesurfer] MNI Coordinates
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?

Re: [Freesurfer] MNI Coordinates
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?

[Freesurfer] Freeview crashes xterm
Hi, I am running freesurfer on a RedHat v6.5 machine (Santiago). I think the installation was successful and the paths are set correctly. However, my xterm crashes when I try to launch freeview. Strangely, the program works as expected when launched remotely via NX. Has anyone encountered this problem before?

Re: [Freesurfer] Freeview crashes xterm
My apologies, I meant the X server crashes, not the xterm.
