The default sPHENIX simulation + reconstruction macro is Fun4All_G4_sPHENIX.C, which is self-explanatory. It is not a black box!. You are welcome to open/edit it to work for your purpose of study.

Try an event display

Then let's see what is implemented by firing up one event:

[jinhuang@rcas2072 sPHENIX]$ source /opt/sphenix/core/bin/sphenix_setup.csh -n   # setup sPHENIX environment if not already done so
# Note, for bash users, please use /opt/sphenix/core/bin/sphenix_setup.sh instead
[jinhuang@rcas2072 sPHENIX]$ root
root [] .x Fun4All_G4_sPHENIX.C(-1) // here negative value in event number start an event display of one event
root [] .L DisplayOn.C 
root [] PHG4Reco* g4 = DisplayOn()
root [] Fun4AllServer *se = Fun4AllServer::instance();
root [] se->run(1)
root [] displaycmd() # this one show more Geant4 command we can run from the ROOT prompt

Run more events

This is simpler, just run with first parameter as the intended number of event:

[jinhuang@rcas2072 sPHENIX]$ source /opt/sphenix/core/bin/sphenix_setup.csh -n   # setup sPHENIX environment if not already done so
[jinhuang@rcas2072 sPHENIX]$ root
root [] .x Fun4All_G4_sPHENIX.C(10) // run 10 events

What next?

Now you are able to run the whole sPHENIX simulation + reconstruction chain. Many next-step topics are listed in the software page. And specifically, to use the simulation for your study, a few thing you might want to try:
