Installation for limit setting (747)

Install CMSSW and Higgs combine

export SCRAM_ARCH=slc6_amd64_gcc491
cmsrel CMSSW_7_4_7
cd CMSSW_7_4_7/src 
cmsenv
git clone https://github.com/cms-analysis/HiggsAnalysis-CombinedLimit.git HiggsAnalysis/CombinedLimit
cd HiggsAnalysis/CombinedLimit
git fetch origin
git checkout v6.3.1
scramv1 b clean; scramv1 b # always make a clean build, as scram doesn't always see updates to src/LinkDef.h
cd ../..

Now install the Hzz2l2nu code

git clone https://github.com/cms2l2v/2l2v_fwk.git UserCode/llvv_fwk
cd UserCode/llvv_fwk
chmod a+x removeUselessFilesForLimit.csh
./removeUselessFilesForLimit.csh
cd ../..
scramv1 b -j 16 

Submit the limit jobs

example for GGH only (for VBF few updates have still to be done by hand in the code)

cd UserCode/llvv_fwk/test/hzz2l2v/computeLimit
python optimize_WideWidth.py -p 4

Get the limit plots

(when the jobs are terminated)

python optimize_WideWidth.py -p 5 
root -l -b -q drawFinalLimits.C

An important note about PR in 80X (2016)

Please before doing your PR, be sure to:

• test your changes
• reverse the changes due to th1fmorph thanks to the following command (and be sure to not add those new files in your git add):

#TO DO before a PR
cd $CMSSW_BASE/src
find UserCode/llvv_fwk/ -type f -name '*.cc' -exec sed -i -e 's/UserCode\/llvv_fwk\/interface\/th1fmorph.h/HiggsAnalysis\/CombinedLimit\/interface\/th1fmorph.h/g' {} \;

• then you can make your PR
• if you want to continue developing, don't forget to reverse this once again:

#TO DO after a PR to be able to continue to work
cd $CMSSW_BASE/src
find UserCode/llvv_fwk/ -type f -name '*.cc' -exec sed -i -e 's/HiggsAnalysis\/CombinedLimit\/interface\/th1fmorph.h/UserCode\/llvv_fwk\/interface\/th1fmorph.h/g' {} \;

For developers

We have decided to use pull-request mode for the master development.

• Fork the code with your personal github ID. See details
• Make a clean git clone in the UserCode directory

cd $CMSSW_BASE/src/UserCode 
git clone [email protected]:yourgithubid/2l2v_fwk.git llvv_fwk
cd llvv_fwk
git remote add upstream [email protected]:cms2l2v/2l2v_fwk.git
git remote update
git merge upstream/master

• Make your own change and commit

git commit -a -m "Added feature A, B, C"
git push

• Make a pull request agains the cms2l2v. See details

For creating private samples

Just use official recipe and produce MINIAOD samples in 76X

Analysing

See example files in UserCode/llvv_fwk/test/hzz2l2nu/ Executing the file 'submit.sh' will run the analysis on all samples defined in 'samples.json'.

Please see the full usage of 'submit.sh' with

./submit.sh

Analysis specific

If you need set your stuff under test/analysis_subdir

In general to run an executable or script you can do:

runLocalAnalysisOverSamples.py -e my_exe -j data/my_samples.json -d my_input_dir -o my_output_dir -c test/runAnalysis_cfg.py.templ -p "@par1=val1 @par2=val2" -s queue

The easiest is however to create a submit.sh script in the directory of your analysis. The executable can also be added in the UserCode/llvv_fwk/test/hzz2l2nu/bin directory (also add it to the Buildfile there)
