This package allows you to produce to flat Ntuples from Delphes PhaseII samples.
If you do not attempt to contribute to this repository, simply clone it:
git clone git@github.com:recotoolsbenchmarks/DelphesNtuplizer.git
If you aim at contributing to the repository, you need to fork this repository (via the fork button) and then clone the forked repository:
git clone git@github.com:YOURGITUSERNAME/DelphesNtuplizer.git
cd DelphesNtuplizer
git remote add upstream git@github.com:recotoolsbenchmarks/DelphesNtuplizer.git
You can then regularly update your fork via:
git fetch upstream && git merge upstream/master
If you want to submit a new feature to recotoolsbenchmarks/DelphesNtuplizer you have to do it via pull-request (PR):
So, first commit and push your changes to YOURGITUSERNAME/DelphesNtuplizer and then make a PR via the github interface.
This package requires Delphes to be installed, and CMSSW for gcc, ROOT, FWLite and other dependencies:
cd DelphesNtuplizer
cmsrel CMSSW_10_0_5
cd CMSSW_10_0_5
cmsenv
cd ..
git clone https://github.com/delphes/delphes.git
cd delphes
./configure
sed -i -e 's/c++0x/c++1y/g' Makefile
make -j 10
cp libDelphes.so ..
Make a dummy test to check Delphes runs properly on GEN-SIM samples (once few events have been processed you can stop processing with CTRL+C):
./DelphesCMSFWLite cards/gen_card.tcl test_gensim.root /eos/cms/store/relval/CMSSW_10_3_0/RelValZMM_13/GEN-SIM-RECO/PU25ns_103X_upgrade2018_realistic_v7-v1/10000/50FEF759-6699-7344-82CE-894E8A724442.root
For producing new validation samples you need to set-up the proper environment
cd CMSSW_10_0_5
cmsenv
cd ../delphes
The Delphes card stored in this repository is configured so that all needed information for validation is available in the Delphes output (gen particles, PF candidates etc ...) As a result, the output size increases substantially compared to normal Delphes samples.
To produce Delphes validation samples run this command (by changing the appropiate input GEN-SIM file of interest):
./DelphesCMSFWLite ../cards/CMS_PhaseII_200PU_v04VAL.tcl delphes.root /eos/cms/store/relval/CMSSW_10_3_0/RelValZMM_13/GEN-SIM-RECO/PU25ns_103X_upgrade2018_realistic_v7-v1/10000/50FEF759-6699-7344-82CE-894E8A724442.root
Set up the proper environment:
cd CMSSW_10_0_5
cmsenv
cd ..
The following command will produce a flat Ntuple, with 10 events.
python bin/Ntuplizer.py -i delphes/delphes.root -o flat_tree.root -n 10
