Thanks, Jim, but I don't think that is the problem. I have other files that linearized just fine, and they list the L* data in descending order exactly as presented below. I did just upgrade to QTR 2.5.2.1, so maybe this is a bug? It's probably something I am doing. Perhaps the two or three darkest patches are too close together. I did notice that the QTR-Linearize- Data version is 2.5.2.0.
