PAT Validation How-To

Overview

  • This page explains how to install and run the PAT validation package.

Installation in CMSSW_3_1_1

To check out and compile the package do:

mkdir PATVALIDATION
cd PATVALIDATION
cmsrel CMSSW_3_1_1
cd CMSSW_3_1_1/src
cmsenv

cvs co Validation/PhysicsTools
scram b

Producing the benchmark plots

  • cd Validation/PhysicsTools/test directory:
  • Either edit benchmark_cfg.py to replace the suitable reco root file or run it as it is, first using the default root file present.
  • Produce the root file with benchmark histograms by doing the following (from the test directory) :
     cmsRun benchmark_cfg.py
  • You get the output file benchmark.root. This root file has a directory with names of different physics object. Each of them is further divided into a PAT and a RECO directory containing PAT and RECO plots that have identical names. The next step is to overlay the plots. For this do
     source validation.sh
This produces the following directories in the test directory : ELECTRONS, PHOTONS, MUONS, JETS, TAUS, MET. One can copy each of these directories straight to a public html area and the plots are visible. The solid colour histograms ( red for electrons, for example) represents the RECO variables whereas the solid bold black histogram represent the PAT variables. Each object has a different colour for RECO variables but the same solid dark black histogram for the PAT variables. I am still working on getting the right templates but the names of the histograms plotted are in the order of what exists in, for example, captions_electrons.electrons text file in the test directory.

To run the validation of each seperately you can use the following scripts in the test directory

validation_electrons.sh  
validation_METs.sh   
validation_photons.sh  
validation_taus.sh
validation_jets.sh       
validation_muons.sh  

Captions for the plots

The caption for the plots is set in the files captions_*****.captions files where ***** can be electrons, jets etc.
