Plotting scripts for LHE, NanoGEN and NanoAOD events

LHE analyzer and plotter

Here are a few scripts to anlyze LHE events with python and NanoGEN events with coffea. It is originally copied from https://github.com/AndreasAlbert/mg5tut_apr21_plots

• To set it up run this:

source env.sh
pip install lhereader matplotlib mplhep 
pip install --upgrade dask
pip install --upgrade numba
pip install coffea 

• Then after each setup, you have to run source env.sh again.

• Run the LHE analyzer:

./lhePlot.py /PathToLHE/cmsgrid_final.lhe -o outDir

NanoGEN analyser

This is a script to analyze NanoGEN events with coffea, as well as simple loop.

• Run NanoGen analyzer:

./nanoGenAna.py /PathTo/NanoGEN/Tree_1.root [-l -o outDir]

NanoAOD analyser for V+Jets study

For this you may need to set up a new environment with conda, installing missing packages (parsl and maybe more). This part is not covered in these instructions.

• After setting the conda environment run this:

./cofeGeno.py -n 1 [-o plots_output_dir] [-e parsl] [-t pre]

it will run over one file (-n 1 option) of each dataset in the file list (hardcoded).

• In order to create a list of files for datasets run this:

./sampleInfo.py mc_vjets_samples.list -o SamplePickleFile.pkl
