+Note that SLCIO files have two records representing truth level MC: MCParticle and MCInfo. MCInfo includes information on generated events.
+See the example how this record was created in [[https://github.com/Argonne-National-Laboratory/ProMC/blob/master/examples/promc2lcio/promc2lcio.java|promc2lcio.java]]
