Thanks for adding this - however I'm using the .pom file differently, only for surface points without fiducials. The reader seems to be looking for fiducials. I bring the fiducials is separately using the Curry .rs3 file (containing electode positions and fiducials). The .pom is only for additional surface points to better correct the co-registrations. Like MEG, only using 3 fiducials seems inadequate, and small errors have even more important consequences. John Mosher wrote earlier about doing it this way.
I had a work around above, so if I'm asking for too specific a change, don't bother with it.
Thanks.
