Installation instructions

To checkout the latest development release:

cd CMSSW_6_2_2/src
cmsenv
git clone git://github.com/L1UpgradeJets/L1UpgradeJetAlgorithm.git .
scram b -j8


Repository contents

The repository contains the following directories:

AnalyseUpgradeJets/ - Contains jet analyser code
SLHCUpgradeSimulations/ - Contains jet emulator code
SimDataFormats/ - Contains jet emulator dataformats

The core of the emulator code is run from the config files in SLHCUpgradeSimulations/L1CaloTrigger/python/: SLHCCaloTrigger_cfi.py SLHCCaloTrigger_cfi.py

Which in turn run modules in: SLHCUpgradeSimulations/L1CaloTrigger/plugins

Running and analysing the L1 upgrade jet algorithm

To run the jet emulator:

• Run the config file ProduceJetCollections.py in the AnalyseUpgradeJets directory: cmsRun ProduceJetCollections.py
• This will by default produce a ROOT file JetCollections.root which contains a large amount of information from: caloTowers and trigger towers to offline and online jet collections and energy sums.

To analyse the output:

• The output of ProduceJetCollections.py can be analysed by running AnalyseJets.py:
  cmsRun AnalyseJets.py
• The input ROOT file given to AnalyseJets.py should be modified to correspond to your file, i.e. edit:
  

process.source = cms.Source("PoolSource",
fileNames = cms.untracked.vstring( 'file:/home/hep/mb1512/JetAnalyser/CMSSW_6_2_2/src/JetCollections.root'),
