git clone git@github.com:BParkHNLs/HNLsGen.git
export CMSSW_SEARCH_PATH=$CMSSW_BASE/src/HNLsGen/evtGenData/:$CMSSW_SEARCH_PATH # needed to use local evt_xx.pdl file

git checkout -b mybranch

After first installation:
cd CMSSW_10_2_15/src/HNLsGen
cmsenv
export PYTHONPATH=$PYTHONPATH:$PWD
This needs to be started from clean CMSSW directory, before cmsenv
- On my laptop, cloned sonia's version of pythia
- compiled there (make)
- copied to t3
- then followed https://twiki.cern.ch/twiki/bin/viewauth/CMS/Pythia8Interface#How_to_setup_the_SCRAM_tool_with
- however does not compile due to imcompatibility between versions 8.230 which is what is used by CMSSSW_10_2_0 and 8.240_sonia
Therefore adopt different strategy:
- start from 8230 version (as obtained from pythia8 website)
- compile on laptop => but then removed in /lib the file
- copy it somewhere on t3
- copy there from sonia's pythia the files she added / changed
- the follow again above mentioend twiki page...
BPH_start_cfg.py => mod tau->3mu with Fall18, starting point
BPH_mod_cfg.py => FROZEN DRIVER, for sharing (version shared with Rome)
step1.py => HNL from B species other than Bc
step1_Bc.py => HNL from Bcs
step1_control.py => control channel generation
Submission to slurm:
cd slurm
Create a VXX_points.py files starting from points.py, then submit
python prodHelper.py --help
The genHelper.py is now deprecated.
We currently shower Bc+ events, starting from LHE files produced by someone else.
The LHE => ROOT conversion is done via cmsDrivers/BHNL_Bc_LHEtoRoot_TEMPLATE.py and submitted via slurm/submitter_lhegen.py
For showering, instead of using the GeneratorFilter, we use the HadronizerFilter, details in cmsDrivers/step1_Bc.py

cd genLevelAnalysis
cmsRun test_ParticleTreeDrawer.py maxEvents=1 inputFiles=file:/work/mratti/GEN_HNL/CMSSW_10_2_15/src/HNLsGen/genSimFiles/BPH-test_HardQCDon.root
To get the gen-level ntuples
cd genLevelAnalysis
python genTreeProducer.py --pl V05_muFromB_pt5_eta1p6_n600000_njt30 --points V05_points.py
To analyze the gen-level ntuples, edit possible options and then run:
python genAnalysis.py --pl V05_muFromB_pt5_eta1p6_n600000_njt30
