Data Card Creator (minimal example from PUAnalysis Framework)

Setup instructions (do only once)

scram project CMSSW CMSSW_10_6_10
cmsenv
readlink -f $(which root)

The last line from the output should show that the environment for ROOT 6.14.09 has been set up. Support for RDataFrame was only added in ROOT 6.14. Notably, ROOT 6.14 does not have the libROOTDataFrame.so library automatically linked in the default libraries (it is in ROOT 6.18, at least), so the BuildFiles in the StatTools folder link the correct library.

Usage

Every time the Data Card Creator is changed, re-compile from the top directory (or from StatTools if something in StatTools was changed):

scram b USER_CXXFLAGS="-Wno-error=unused-but-set-variable"

Standard TTree->Draw() version

To run the minimal example of the original Data Card Creator:

cd StatTools/data
bash makePlot

RDataFrame example

cd StatTools/data
bash makePlot_RDF

If the verbose option is on/ something is written to std::cout, it's a good idea to pipe the std::cout to a text file to check if the histogram yields and number of entries remain unchanged as one iterates through edits:

sort out.txt > out.sorted
sort outRDF.txt > outRDF.sorted
diff -y out.sorted outRDF.sorted

Boost example (in-development)

If using a virtual environment on lxplus, just pip install boost-histogram. If you are not using environments, you can do a user install (--user), which is not as good as an environmental in general, but works.
