/*
Quick Start:

1. Start train macro (real data from GSI::SE). Source your own Alien environment.

source /u/jacek/alien/set_alien_env.sh
aliroot -b -q 'RunPerformanceTrain.C("AliESDs.root",2,kFALSE,kTRUE,kTRUE)'

3. Start train macro (real data from lustre)

aliroot -b -q 'RunPerformanceTrain.C("AliESDs.root",2,kFALSE,kTRUE,kFALSE)'
