-[[http://atlaswww.hep.anl.gov/hepsim/HepSim | HepSim]] repository provides a number of truth-level MC samples for signal and background that can be used as inputs for a fast simulation. The analysis can be done as explained in  [[https://atlaswww.hep.anl.gov/asc/wikidoc/doku.php?id=community:refhepsim |this manual]].

 Let us make 2 runs: One run  will use the first geometry layout, and the second run will use the 2nd input card.
