This Package was built with the help of the tutorial: https://twiki.cern.ch/twiki/bin/view/AtlasComputing/SoftwareTutorialxAODAnalysisInROOT

It actually works on AnalysisBase 2.3.11:

rcSetup Base,2.3.11

It didn't with newer version but I'm sure that it should also work.

To compile: rc find_packages rc compile

The package contains one class called TruthReader. This is the code which read TRUTH1 xAOD and built histograms from it. The output will be a .root file containing all the histograms Then, one can treat this root file, to set his own style and draw it in whatever format. The package Atlas* class are there to build histograms with Atlas Style.

The util/ folder contains all the code to execute. TruthPlot use the call TruthReader to build a folder which contains the output histograms MergeHisto is my own code which plot both histogram in one single histogram with a ratio plot. But I would suggest that you build your own code for that.

In the script/ folder, you can find a example launch.sh which create a validation pdf file with two samples

To use TruthPlot, do :

TruthPlot InputFolder/ Truth1_Input_xAOD.root OutputFolder/

When running this code, Make sure that the OutputFolder doesn't already exist !!!! It won't work otherwise Then you can find your .root output file in the OutputFoder/

To plot histograms from 2 samples in one pdf file, do :

MergeHisto Sample1.root Sample2.root Output.pdf
