# A script producing a consistent MC->RECO->AOD workflow
# It aims to handle the different MC possible configurations
# It just creates a workflow.json txt file, to execute the workflow one must execute right after

# Execution examples:
#  - pp PYTHIA jets, 2 events, triggered on high pT decay photons on all barrel calorimeters acceptance, eCMS 13 TeV
#     ./o2dpg_sim_workflow.py -e TGeant3 -ns 2 -j 8 -tf 1 -col pp -eCM 13000 \

#  - pp PYTHIA ccbar events embedded into heavy-ion environment, 2 PYTHIA events into 1 bkg event, beams energy 2.510
