What can I do to help diagnose the problem. I know this is not reproducible, but I don't know without sharing the entire data set how to do that. Thanks in advance -- Stephen Sefick Research Scientist Southeastern Natural Sciences Academy Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K.
