Setting up combine

You need to install the CombineHarvester package by following these and these instructions. In general, the CMSSW area where the combine toolset is built can be different from the CMSSW area where the analysis is run.

For auxiliary measurements

# open up a new shell session

cmsrel CMSSW_10_2_13
cd $_/src
cmsenv
git clone https://github.com/cms-analysis/HiggsAnalysis-CombinedLimit.git $CMSSW_BASE/src/HiggsAnalysis/CombinedLimit

# IMPORTANT: Checkout the recommended tag on the link above
cd $CMSSW_BASE/src/HiggsAnalysis/CombinedLimit
git fetch origin
git checkout v8.0.1

git clone https://github.com/cms-analysis/CombineHarvester $CMSSW_BASE/src/CombineHarvester

cd $CMSSW_BASE/src
scram b clean -j8 && scram b -j8

The instructions for lepton fake rate analysis stop here, but for the charge flip rate, the following package has to be cloned (in the same CMSSW area where combine resides):

git clone https://github.com/HEP-KBFI/tth_charge-flip_estimation $CMSSW_BASE/src/tthAnalysis/ChargeFlipEstimation

For analysis post-fits

# open up a new shell session

cmsrel CMSSW_8_1_0
cd $_/src
cmsenv
git clone https://github.com/cms-analysis/HiggsAnalysis-CombinedLimit.git $CMSSW_BASE/src/HiggsAnalysis/CombinedLimit

# IMPORTANT: Checkout the recommended tag on the link above
cd $CMSSW_BASE/src/HiggsAnalysis/CombinedLimit
git fetch origin
git checkout v7.0.13

git clone https://github.com/HEP-KBFI/CombineHarvester $CMSSW_BASE/src/CombineHarvester

cd $CMSSW_BASE/src
scram b clean -j8 && scram b -j8
