Hi, You also can try the MR program Queen of Spades (Qs) ( http://utopia.duth.gr/~glykos/Qs.html; documentation, http://utopia.duth.gr/~glykos/pdf/Qs.pdf). It is a multi-dimensional MR, so it will use a lot of CPU time and memory, but might be worth try it. Good luck. Andrey Nascimento 2013/4/18

I am agree with Tassos. For me it is a quite stranger to think about hide the data to nobody see until the paper be published. In my opinion, a lot of data become obsolete (or even forgotten) because that "one more" experiment you need to publish a "great" paper (it some times takes years...). For
