====== Creating single particle samples ======

Single particle samples are created using the ProMC Java package.
Here is an example how to make single particle sample using Jython {{:community:hepsim:particle_gun.py|particle_gun.py}}.

You can use [[https://atlaswww.hep.anl.gov/asc/jas4pp/|Jas4pp]] to run this script:

<code bash>
wget --no-check-certificate https://atlaswww.hep.anl.gov/asc/wikidoc/lib/exe/fetch.php?media=community:hepsim:particle_gun.py -O particle_gun.py
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 [[http://jwork.org/dmelt/code/index.php?keyword=particle_gun|Dmelt example]] page. You will need to run either DMelt or Jas4pp to create single-particle sample using the Jython script.
