 HepSim is optimized to keep truth-level in the "archive" format called [[asc:promc|ProMC]]. It allows to keep data in a compact form optimized for data streaming over the network, together with logfiles which will help to identify the MC settings.
-ProMC files can be created directly by Pythi8 (the example "main46.cc" in the Pythi8). Or, you can convert files in the format "HEPMC", "LHE", "STDHEP" to ProMC as shown in the "example" directory of the installed ProMC package (look at $PROMC/examples). The converters are:

+ProMC files can be created directly by Pythia8. Look at the example "examples/main46.ccmain46.cc" inside the Pythi8 distribution. To compile it,
+please  install [[https://atlaswww.hep.anl.gov/asc/wikidoc/doku.php?id=asc:promc:installation|ProMC package]] first, before running configuration script
+of Pythia8. If the environmental variable "PROMC" was set, then you can compile "main46.cc" example.
