• Bambu -> Code to produce from Bambu.

Nero

The Nero directory contains the ntuple producer. It is designed to run on MiniAOD within the CMSSW framework.

CMSSW compile

• Notice that cmssw should be init when the src directory is empty. Currently the supported version are CMSSW_7_4_15_patch1 (checking out the branch 74X) and CMSSW_7_6_3_patch2 (master).

cmsrel CMSSW_7_6_3_patch2
cd CMSSW_7_6_3_patch2/src
cmsenv
wget --no-check-certificate 'https://raw.githubusercontent.com/MiT-HEP/NeroProducer/master/Nero/script/setup.sh' -O /tmp/$USER/setup.sh
source /tmp/$USER/setup.sh

• Clone the git repository and compile it

cd ${CMSSW_BASE}/src
git clone [email protected]:MiT-HEP/NeroProducer.git
cd ${CMSSW_BASE}/srcNeroProducer/Nero
scram b -j 16
cd ${CMSSW_BASE}/src/NeroProducer/Skim
scram b -j 16
cd ${CMSSW_BASE}/src/NeroProducer/Core
scram b -j 16

How to Run

If running on data, set the isData flag to True, else False.

cd NeroProducer/Nero/test
cmsRun testNero.py isData=True

To check the simple cut flow for the monojet analysis

cd NeroProducer/Nero/scripts
./cutflow.py -f FILENAME -n NUMBEROFEVENTS

The numbers should match: https://twiki.cern.ch/twiki/bin/view/CMS/DMS13TeVSynch

Crab submit

cd NeroProducer/Nero/test

edit crabCfg.py to use test/testNero.py crab submit

Batch submit

• MINIAOD
• edit the ../test/testNero.py to be sure to use the right configuration (ChargedHiggs or MonoJet)

cd NeroProducer/Nero/script
dir=TT_Tune4C_13TeV-pythia8-tauola;vers=v0.2; python sendOnBatch.py -i ../test/testNero.py -e /store/mc/Phys14DR/${dir} --put-in=/store/user/${USER}/Nero/${vers}/${dir} -d ${dir} -n 100 -q 8nh

• MINIAOD-SKIMMED
• edit the ../test/testNeroSkimmed.py to be sure to use the right configuration (ChargedHiggs or MonoJet)

cd NeroProducer/Nero/script
vers=v0.2;dir=TTbar_HBWB_HToTauNu_M-90_13TeV_pythia6 ;python sendOnBatch.py -i ../test/testNeroSkimmed.py -e /store/user/amarini/v0.1/${dir} --put-in=/store/user/amarini/Nero/${vers}/${dir} -d ${dir} -n 10 -q 8nh

Grid submit

• MINIAOD
• edit test/crabNero.py to match the datasets you want

python crabNero.py

• check the status with

python multicrab.py  -c status -w NeroSubmission

or

crab status NeroSubmission/mydir

Core

Core can be either compiled within CMSSW or standalone.

• Compile

cd NeroProducer/Core
make -j 16

• Use it, for example

root
gSystem->Load("bin/libBare.so");
TChain *f = new TChain("nero/events")
f->Add("~/eos/cms/store/user/amarini/Nero/v0.2/TTbar_HBWB_HToTauNu_M-90_13TeV_pythia6/NeroNtuples_*root")

BareJets *j = new BareJets()
j->setBranchAddresses(f)

BarePhotons *p = new BarePhotons()
p->setBranchAddresses(f)

f->GetEntry(0)

j->p4->GetEntries()
((TLorentzVector*)j->p4->At(0))->Pt()

Skim

CMSSW compile

cmsenv
cd NeroProducer/Skim
scram b -j 16

Crab submit

cd NeroProducer/Nero/test

edit crabCfg.py to use test/runSkim.py
