Hi Holly,
If you can - look at your individual image with display/image, find
the fiducial locations carefully, write them down and then use the
'type' option. That'd be more precise. The standard locations are
obtained by inverse-transforming template fiducials which might be
imprecise.
Best,
Vladimir
