Dear sir,

I’m going to process as follows:

I have a point on the surface ("Vertex RAS" in tksurfer) and want tocompute the Scanner RAS in orig.mgz that corresponds to this point:ScannerRAS = Norig*inv(Torig)*[tkrR tkrA tkrS 1]

If vertex RAS is x=10 y=20 z=30, [tkrR tkrA tkrS 1] is [10 0 0 1;  0 20 0 1; 0 0 30 1], right?

I don’t know how I use [tkrR tkrA tkrS 1].  Please let me know.

Thanks
