Framework for tau analysis using NanoAOD at CMS. Three main packages are
PicoProducer
: Tools to process nanoAOD and make custom analysis ntuples.Plotter
: Tools for further analysis, auxiliary measurements, validation and plotting.Fitter
: Tools for measurements and fits in combine. [Under development.]
First, setup a CMSSW release. For example,
nanoAODv10 (python3) | Older versions (python2) |
export CMSSW=CMSSW_12_4_8
export SCRAM_ARCH=slc7_amd64_gcc10
cmsrel $CMSSW
cd $CMSSW/src
cmsenv |
export CMSSW=CMSSW_11_3_4
export SCRAM_ARCH=slc7_amd64_gcc900
cmsrel $CMSSW
cd $CMSSW/src
cmsenv |
On a Linux 8 node like lxplus8
, you can use the el8_amd64_gcc10
architecture instead of slc7_*
.
Which CMSSW release should not really matter for post-processing of nanoAOD,
but if you like to use combine
in the same repository, it is better to use at least the
recommended release for the latest Combine version,
see below.
To install TauFW
:
cd $CMSSW_BASE/src/
git clone https://github.com/cms-tau-pog/TauFW TauFW
scram b -j4
With each new session, do
export SCRAM_ARCH=slc7_amd64_gcc700
cd $CMSSW/src
cmsenv
If you want to process nanoAOD using PicoProducer
, install NanoAODTools
:
cd $CMSSW_BASE/src/
git clone https://github.com/cms-nanoAOD/nanoAOD-tools.git PhysicsTools/NanoAODTools
scram b -j4
If you want to use tau ID SFs, please install TauIDSFs
tool:
cd $CMSSW_BASE/src/
git clone https://github.com/cms-tau-pog/TauIDSFs TauPOG/TauIDSFs
cmsenv
scram b -j4
If you want to use the lepton SFs from the HTT group, please do
cd $CMSSW_BASE/src/TauFW/PicoProducer/data/lepton/
rm -rf HTT
git clone https://github.com/CMS-HTT/LeptonEfficiencies HTT
If you want to use the combine
tools in Fitter
, install combine following the
latest instructions,
for example
cd $CMSSW_BASE/src
git clone https://github.com/cms-analysis/HiggsAnalysis-CombinedLimit.git HiggsAnalysis/CombinedLimit
cd HiggsAnalysis/CombinedLimit
git fetch origin
git checkout v8.1.0 # for CMSSW_10_X
git checkout v9.1.0 # for CMSSW_11_X
and then CombineHarvester
,
cd $CMSSW_BASE/src
git clone https://github.com/cms-analysis/CombineHarvester.git CombineHarvester
scramv1 b clean; scramv1 b
git checkout v2.0.0 # for CMSSW_11_X only
For TauPOG-internal work: To create JSON files with TauPOG corrections for
correctionlib
,
please follow the instructions
here.
From at least CMSSW_11_3_X
, correctionlib
should be pre-installed.
To create ROOT files including the measured SFs please install TauIDSFs
tool.
Modify the TauIDSFs/utils/createSFFiles.py
script to include your measured SFs into the script.
Finally, run the TauFW/scripts/tau_createROOT.sh
to generate your ROOT files. They will be created into TauFW/scripts/data/
IMPORTANT: please comment and do not delete older SFs
The latest code used to create root files for SF can be taken from here
