Open HLT Trigger study for Heavy Ion

How to run Open HLT

  • Open HLT uses the samples done by HLTAnalyzer, which is kind of ntuple maker
  • How to run HLTAnalyzer

cvs co HLTrigger/HLTanalyzers/
cd HLTrigger/HLTanalyzers/test
  • then you can find some of root files, which includes ntuples such as L1MuOpen? bit and MuPt? etc..

When running in 35X:

scramv1 project CMSSW CMSSW_3_5_7
cd CMSSW_3_5_7/src
project CMSSW
addpkg HLTrigger/HLTanalyzers
scramv1 b
cd HLTrigger/HLTanalyzers/test

Note: starting from 35X releases, the default settings are configured for running on real data (meaning the process name, global tag, and name of the RAW data collection), with the 8E29-style menu. This can be changed using the "isData" and "MENU" parameters in

Input : Can be output of HLTtable.cfg (Output of an EDProducer), or simple RAW file, or both together. includes all modules and paths specific to the OpenHLT mode.

Ouput : openhlt.root roottuple :


Default Running
cvs co -r RateEff-02-01-01 HLTrigger/HLTanalyzers/test/
cd HLTrigger/HLTanalyzers/test/RateEff
tar zxvf libconfig-1.3.tar.gz
cd libconfig-1.3
cd ../
source setup.csh(sh)
./OHltRateEff hltmenu_8E29_2009May11.cfg

Heavy Ion Running
To run:
cd $CMSSW_BASE/src/HLTrigger/HLTanalyzers/test
cvs co -r RateEff-HI-0-1
mv UserCode/HIHLTStudy/HLTrigger/HLTanalyzers/test/RateEff .

cd RateEff
tar xvzf libconfig-1.3.tar.gz
cd libconfig-1.3/
cd ../


./OHltRateEff hltmenu_HIon_2009Sep.cfg

Open HLT setup


  • Setup your working environment:
    # CMSSW_3_2_4
    scramv1 project CMSSW CMSSW_3_2_4
    cd CMSSW_3_2_4/src
    # Check out from CVS
    cvs co UserCode/HIHLTStudy
    mv UserCode/HIHLTStudy/* .
    # genparticle and genjet 32x code
    cvs co -r cmshi_32X UserCode/CmsHi/JetAnalysis
    cvs co -r V00-01-02 UserCode/CmsHi/Utilities
    cvs co -r V00-01-02 DataFormats/HeavyIonEvent
    mv UserCode/CmsHi .
    # Build
    scramv1 b -j 4
  • The lastesting working tag is: HIOpenHLT_1_2
    • Includes: jet and photon parts can run
