Welcome

This is the standard macros respository for ECCE. Following is the 10-min tutorial on using the default macros.

Get started

Please follow software day-1 checklist to get started.

Check out macro repository

Download the newest macro repository from GitHub:

The default EIC detector simulation + reconstruction macro is detectors/EICDetector/Fun4All_G4_EICDetector.C, which is a collection of steering flags that drives the common macros. They are not a black box!. You are welcome to open/edit it to work for your purpose of study.

Try an event display

Please edit Fun4All_G4_EICDetector.C to change flag Enable::DISPLAY = true; Then let's see what is implemented by firing up one event:

[EICDetector]$ source /cvmfs/eic.opensciencegrid.org/ecce/gcc-8.3/opt/fun4all/core/bin/ecce_setup.sh -n   # setup environment if not already done so
# Note, for csh users, please use /cvmfs/eic.opensciencegrid.org/ecce/gcc-8.3/opt/fun4all/core/bin/ecce_setup.csh instead
[EICDetector]$ root
root [] .x Fun4All_G4_EICDetector.C // here negative value in event number start an event display of one event
root [] se->run(1)
root [] g4->ApplyCommand("/vis/viewer/refresh");
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:

[EICDetector]$ source /cvmfs/eic.opensciencegrid.org/ecce/gcc-8.3/opt/fun4all/core/bin/ecce_setup.sh -n   # setup sPHENIX environment if not already done so
Please recover Enable::DISPLAY = false; as in Fun4All_G4_EICDetector.C 
[EICDetector]$ root
root [] .x Fun4All_G4_EICDetector.C(10) // run 10 events

What next?

Now you are able to run the whole 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:
