Thanks Barry, that works fine. Any chance to access the reordered matrix behind the plot?

Now I would like to compare with a reordened pattern, say rcm. I've notice the option -mat_view_ordering draw, but do not have X Windows on this machine. What is the recommended way to get the reordened matrix for inspection? Chris <image859244.png> dr. ir.
