Great, thanks! > Could you please send me privately the actual input file on which the > program crashes? Well, it compresses to 1511 bytes, so I risk attaching it here for simplicity. > I have added a downloadable link to the presentation to all places > where the slideshare link was present (finally making some use of my > hosting...). > Here it is: http://jkff.info/presentations/two-visualization-tools.pdf Wonderful, thanks a lot! -- Regards, Feri.
