When reaching the step that executes make_plots.py the following error arises:

[chpapage@cmslpc157 SUEP_Analysis]$ python util/make_plots.py 
Traceback (most recent call last):

Hi Christos, in the setup.sh script if you chance this line source /cvmfs/cms.cern.ch/slc7_amd64_gcc530/lcg/root/6.08.07-njopjo/bin/thisroot.sh to this source /cvmfs/sft.cern.ch/lcg/views/LCG_97rc4/x86_64-centos7-gcc9-opt/setup.sh

you should be able to compile and do python util/make_plots.py

Okay! I was using the cmssw branch where the setup file is different. I think it deserves a special setupROOT.sh script since it can interfere with compilation.
