How to set up the analysis machinery

Hi all!

with Emanuele, we tried to summarize the steps which are needed to setup the machinery for the analysis. Here is a (hopefully) working recipe:

scramv1 project CMSSW CMSSW_1_3_1_HLT5
cd CMSSW_1_3_1_HLT5/src
eval `scramv1 ru -csh`
project CMSSW

# extra tags for the trigger
cvs co -r V00-01-44 HLTrigger/Configuration
cvs co -r V00-00-20-09 L1Trigger/RegionalCaloTrigger
cvs co -r V01-00-14 L1Trigger/L1ExtraFromDigis
cvs co -r V00-00-38 RecoEgamma/EgammaHLTProducers
cvs co -r V00-01-10 Utilities/ReleaseScripts
cvs co -r V00-05-02-02 RecoMuon/L2MuonProducer
cvs co -r V00-00-53 HLTrigger/Egamma
cvs co -r V00-01-50 HLTrigger/Muon
cvs co -r V00-00-87 HLTrigger/btau
cvs co -r V00-00-49 HLTrigger/xchannel
cvs co -r V00-00-07-18 HLTrigger/JetMET
cvs co -r V01-03-26 HLTrigger/HLTcore
cvs co -r V00-01-44 HLTrigger/Configuration
cvs co -r V04-01-00-01 CalibTracker/SiStripConnectivity
cvs co -r V01-00-00-02 CommonTools/SiStripClusterization
cvs co -r V03-04-02 DataFormats/SiStripCluster
cvs co -r V03-05-02-01 DataFormats/SiStripCommon
cvs co -r V01-02-05-00 DataFormats/TrackerRecHit2D
cvs co -r V02-00-00-05 EventFilter/SiStripRawToDigi
cvs co -r V01-04-04-01 RecoLocalTracker/SiStripRecHitConverter
cvs co -r V05-00-40-01 RecoTracker/MeasurementDet
cvs co -r V01-02-01-00 RecoTracker/TransientTrackingRecHit


# bug fix in 131 for electron reconstruction:
cvs co -r CMSSW_1_3_1 DataFormats/EgammaCandidates
edit DataFormats/EgammaCandidates/src/PixelMatchGsfElectron.cc
and replace line 196 hadOverEm_*=newEnergy/superClusterEnergy_;
with hadOverEm_*=superClusterEnergy_/newEnergy


# fix for NAN in particle time of flight
cvs co -r CMSSW_1_3_1 SimCalorimetry/CaloSimAlgos

edit SimCalorimetry/CaloSimAlgos/src/CaloHitResponse.cc
and add [see the head, in case] in 'run'

// check the hit time makes sense
if ( isnan(((*hitItr).time())) ) { continue; }



# to use new variables for shower shape:
source cvs_setup_pietro
cvs co -r V01-01 DataFormats/EgammaReco
cvs co -r V01-01 RecoEcal/EgammaCoreTools
cvs co -r V131_HLT5 PhysicsTools

# and finally download the code:
cvs co HtoWWElectrons


Ciao!
