EGTagAndProbe

Set of tools to evaluate L1EG trigger performance on TnP

Taken from https://gitlab.cern.ch/ckoraka/EGTagAndProbe

Install instructions

To run on 2018 data follow L1 Trigger Emulator Stage 2 Upgrade Instructions located here [1], and also given bellow

cmsrel CMSSW_11_0_2
cd CMSSW_11_0_2/src
cmsenv
git cms-init
git remote add cms-l1t-offline [email protected]:cms-l1t-offline/cmssw.git
git fetch cms-l1t-offline l1t-integration-CMSSW_11_0_2
git cms-merge-topic -u cms-l1t-offline:l1t-integration-v104.5
git cms-addpkg L1Trigger/L1TCommon
git cms-addpkg L1Trigger/L1TMuon
git clone https://github.com/cms-l1t-offline/L1Trigger-L1TMuon.git L1Trigger/L1TMuon/data
git cms-addpkg L1Trigger/L1TCalorimeter
git clone https://github.com/cms-l1t-offline/L1Trigger-L1TCalorimeter.git L1Trigger/L1TCalorimeter/data

scram b -j 8

Then clone the repository:

git clone https://github.com/mkovac/L1EgammaPerformance.git
scram b -j 4

Now you have set up the work directory. You should go to the L1EgammaPerformance/TagAndProbe/test directory and run scripts there.

Producing TagAndProbe ntuples with unpacked L1EG (no re-emulation)

• Set flag isMC and isMINIAOD in TnP_L1.py, depending on what kind of dataset you are running on.
• HLT path used specified in python/MCAnalysis_cff.py (MC) or python/tagAndProbe_cff.py (data)
• Launch TnP_L1.py

Producing TagAndProbe ntuples with emulated L1EG

Here is a checklist of code you need to modify in order to run your desired process.

• Update electron ID to be exactly the same ones used in the data.
• Make sure you use L1TReEmulFromRawsimEcalTP(process) instead of L1TReEmulFromRaw(process). Corresponding lines in TnP_emulate_L1.py are:

from L1Trigger.Configuration.customiseReEmul import L1TReEmulFromRAWsimEcalTP
process = L1TReEmulFromRAWsimEcalTP(process)

• Use the correct Calo parameters according to your run number. See L1 Known Issues. You can edit this in the line:process.load("L1Trigger.L1TCalorimeter.caloParams_2018_v1_3_cfi") in the TnP_emulate_L1.py.
• Be sure to use the correct sqlite file (with extension .db) in your TnP_emulate_L1.py

Submit job on the Grid

Modify Crab3_TnP_<>.py: change requestName, inputDataSet, outLFNDirBase, outputDatasetTag, storageSite

cd $CMSSW_BASE/src/L1EgammaPerformance/TagAndProbe/test
source /cvmfs/cms.cern.ch/crab3/crab.sh
voms-proxy-init -voms cms
crab submit -c Crab3_TnP_<>.py

Producing turn-on plots

Create configuration file based on $CMSSW_BASE/src/L1EgammaPerformance/TagAndProbe/test/fitter/run/Parameters_16_16.par

cd $CMSSW_BASE/src/L1EgammaPerformance/TagAndProbe/test/fitter
make clean
make
./fit.exe run/Parameters_16_16.par

Note that you need to modify the input file location in the .par file.

Create plotting script based on $CMSSW_BASE/src/L1EgammaPerformance/TagAndProbe/test/fitter/results/plot_EG_16_16.py

cd $CMSSW_BASE/src/L1EgammaPerformance/TagAndProbe/test/fitter/results
python plot_EG_16_16.py
