This should be in the format provided by http://opendata.cern.ch.
See example below.
-m | --maxparticles VALUE
Get only events for which its number of particles does not exceed VALUE.
Get only events for which its number of particles does not
exceed VALUE.
--minparticles VALUE
Get only events for which its number of particles is greater than or equal to VALUE.
Get only events for which its number of particles is greater than
or equal to VALUE.
-n | --numberofevents VALUE
Set number of events to be animated inside chosen ESD file.
--minavgpz VALUE
Get only events for which its absolute value of average momentum in
the z direction is greater than or equal to VALUE. Useful for animating
events with 'boosts' of particles to the same side.
-t | --duration VALUE
Set the animation duration in seconds.
