   * 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]].

 +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.
