Thanks again for a great explanation John, I knew all this but I think that my frustration currently stems from being stuck between a rock and a hard place. We can't use EigenD as you have been using it, and the user-friendly and streamlined interface hasn't been released yet. So as we continue to be more proficient with the Eigenharp, this status quo becomes a problem ... and I suppose that we should just be patient. However, as most humans, I'm impatient by nature :-)
