+====== Creating single particles ======
+Single particle samples are created using the ProMC Java package.
+Here is an example how to make single particle sample using Jython {{:hepsim:particle_gun.py|particle_gun.py}}.
+You can use [[https://atlaswww.hep.anl.gov/asc/jas4pp/|Jas4pp]] to run this script:
+<code bash>
+fpad particle_gun.py # run this script using Jas4pp
+</code>
+The last  command creates 1000 single-pion events with random Eta, Phi and momenta.
+You can modify this script to change pT, Eta etc.
+An example implemented in Jython is also given in [[https://datamelt.org/code/index.php?keyword=particle_gun|Datamelt example]] page. You will need to run either DataMelt or Jas4pp to create single-particle sample using the Jython script.
