KUEWKinoAnalysis code package implementing the KU EWKino Analysis
In order for the KUEWKinoAnalysis package to build the BuildFit.x executable,
the user must make sure that CMSSW is available and include the KEWKinoAnalysis package
in the correct location in the CMSSW directory structure.
You will also need the CombineHarvester and HiggsAnalysis CMSSW packages.
These packages must be included in the CMSSW directory structure as:
- CMSSW_Z_Y_X
- src
- CombineHarvester
- HiggsAnalysis
- KUEWKinoAnalysis
You can setup a CMSSW area and checkout the required packages by performing the terminal commands below.
These instructions are for bash users.
Bash is recommended, as framework scripts for other shells are not created/supported.
You can check what shell you are using by running echo $0 or echo $SHELL.
Put these commands in either ~/.bash_profile or ~/.bashrc (but not both)
so that they are run at the beginning of every new terminal session:
source /cvmfs/cms.cern.ch/cmsset_default.sh
source /cvmfs/cms.cern.ch/crab3/crab.sh
export SCRAM_ARCH=slc7_amd64_gcc700
Once these commands are added to ~/.bash_profile or ~/.bashrc for the first time,
you can then source whichever file was modified to apply these changes.
source ~/.bash_profile
source ~/.bashrc
Note that assigning this SCRAM_ARCH (slc7_amd64_gcc700) is required before checking out CMSSW_10_6_5 so that the framework can compile successfully. For this use case, SCRAM_ARCH does matter! Compile errors have been observed in KUEWKinoAnalysis when SCRAM_ARCH is not set before checking out CMSSW_10_6_5.
Checkout CMSSW_10_6_5.
cmsrel CMSSW_10_6_5
cd CMSSW_10_6_5/src
cmsenv
Download these repos in the CMSSW_10_6_5/src directory.
Use the KU branch of HiggsAnalysis, the connect branch of CombineHarvester, and the master branch of KUEWKinoAnalysis.
git clone -b KU https://github.com/zflowers/HiggsAnalysis-CombinedLimit.git HiggsAnalysis/CombinedLimit
git clone -b connect https://github.com/zflowers/CombineHarvester.git CombineHarvester
git clone -b master https://github.com/crogan/KUEWKinoAnalysis.git KUEWKinoAnalysis
Setup the RestFrames framework in the CMSSW_10_6_5/src directory.
wget --no-check-certificate http://stash.osgconnect.net/+zflowers/RestFrames_vNew.tar
tar -xvf RestFrames_vNew.tar
cd RestFrames
./configure --prefix=$CMSSW_BASE/src/restframe_build
make -j8
make install
cd ..
Build the CMSSW packages from the CMSSW_10_6_5/src directory.
scram b -j8
Then build KUEWKinoAnalysis (with the BuildFit.x executable).
Note that you will need to run the RestFrames setup script
(in this case the one specific to CMS connect) before compiling.
Also note that we compile using CMSSW, which is required.
Compile and run issues have been observed when compiling without CMSSW.
cd KUEWKinoAnalysis
source scripts/setup_RestFrames_connect.sh
make clean && make cmssw -j8
To run text2workspace (T2W): Go to the directory with the datacard for a given mass point
combineTool.py -M T2W -i datacard.txt -m MASS_Value --job-mode connect -o workspace.root --input-file ../../../FitInput_KUEWKino_2017.root --sub-opts='+ProjectName=cms.org.ku" \n request_memory = 8 GB \n'
Note that mass value will typically be the name of the directory that the datacard is in (ex: 5000325) and the input file is the path to the output root file from BuildFit.x
To run AsymptoticLimits: Go to the directory that was the output of BuildFit.x
combineTool.py -M AsymptoticLimits -d */*/*/datacard.txt --job-mode connect --input-file FitInput_KUEWKino_2017.root --sub-opts='+ProjectName="cms.org.ku" \n request_memory = 8 GB \n'
To run impacts: Go to the directory that the workspace (and datacard) live in
combineTool.py -M Impacts -d workspace.root -m MASS_Value --doInitialFit --robustFit 1 --job-mode connect --sub-opts='+ProjectName="cms.org.ku" \n request_memory = 8 GB \n'
combineTool.py -M Impacts -d workspace.root -m 5000325 --input-file ../ --job-mode connect --sub-opts='+ProjectName="cms.org.ku" \n request_memory = 8 GB \n'
Note that the second step only should be ran after the jobs in the first step finish The input file is just the entire directory that the workspace lives in
