-====== How to analyse Monte Carlo event samples ======
+====== Analysing Monte Carlo events ======
+The Monte Carlo files (truth level, fast simulations and full simulations)
+ can be accessed from the [[http://atlaswww.hep.anl.gov/hepsim/ | HepSim repository]] link.
+Currently these studies are based on  [[http://atlaswww.hep.anl.gov/asc/jas4pp|Jas4pp data-analysis environment]].
+Geometry files for full detector simulations can be found in the  [[http://atlaswww.hep.anl.gov/hepsim/soft/detectors/|detector repository]].
+You have several choices for data analysis:
+  * Using the hs-tools package as described in [[http://atlaswww.hep.anl.gov/hepsim/description.php|short description]]. It is designed for downloading files and processing truth-level files using Python/Jython scripts (or using Java)
+  * Using [[http://atlaswww.hep.anl.gov/asc/jas4pp/|Jas4pp]]. It is similar to the above package, but it has packages needed to process full-simulation samples (SLCIO files).
+  * Using C++/ROOT. If you run over ProMC (truth-level) files, look at the manual [[asc:promc|ProMC manual]]. If you run over ROOT files from Delphes, use [[https://cp3.irmp.ucl.ac.be/projects/delphes|Delphes manual]]. If you analyse LCIO files with full simulation, look at [[http://lcio.desy.de/v01-07/doc/manual_html/manual.html|LCIO manual]].
+Some analysis examples implemented in Python and C++ can be found in [[fcs:fcchh:intro|here]]. Also look for specific topics given below.
+======  Finding detector simulations  ======
+Every entry in the HepSim has "truth-level" files (created by Monte Carlo generators) and reconstruction tags: Data after processing
+by the fast simulation program (Delphes) have the tag "rfastNNN" (NNN is a number), while data after full simulation have the tag "rfullNNN" (NNN is a number). The info pages for each sample has the link to the tag and the information page describing the detector.
+If you need to find all samples for a given tag, use the [[http://atlaswww.hep.anl.gov/hepsim/search.php|search page]]. Then type the tag name.
+For example, if you are searching for the "**rfull006**" reconstruction tag, this page  returns a complete list of Monte Carlo samples which were processed for a given detector.

 This manual describes how to work with truth-level samples posted on HepSim.
 [[https://atlaswww.hep.anl.gov/asc/wikidoc/doku.php?id=community:refhepsim_analysis|HepSim Python/Java analysis page]] explains how to write code to read truth-level files using Python on the Java platform.
