Dear Nikhil, Success! I believe I have the configuration right. Now I just need to add a wand.
By the way, I may have found a bug / feature. It seems like I have to specify the eye separation value in mm, even though I have transformed my tracker units to metres in the state file. Perhaps this is another mistake in my configuration though. Please let me know if that's the case. Thanks very much for all your help Seán
