# Recipe from the RECO/DIGI part of HCAL:

# has a useful script for MC generation

# Download SinglePi_Phase1.sh from the twiki above and copy it into local directory
sh ./SinglePi_Phase1.sh -m 2
# Have a look at SinglePiE50HCAL_pythia8_cfi_GEN_SIM.py while the script is running
# Look for "Pythia8EGun" to modify parameters (to shoot π or e into HF)

# To run with new settings:
cmsRun SinglePiE50HCAL_pythia8_cfi_GEN_SIM.py
cmsRun step2*.py
cmsRun step3*.py

# Useful collections (in i.e. step3.root):
# * genParticles
# * HFRecHitsSorted hfreco (empty for me)
# * HFPreRecHitsSorted hfprereco (are filled for me) long fiber: depths 1, 3; short fiber: depths 2, 4
# In step2.root:
# * simHcalTriggerPrimitiveDigis (HF: version 1; tp.id().version() == 1)
