Introduction

This article describes how to use L1CaloUpgradeHistoMaker to make .root files with basic histograms starting from the MSU ntuple maker output.

Instructions

1) cd into the AnalysisTools directory

cd /path/to/L1CaloUpgrade/AnalysisTools/

2) start root and load the .C file

root
.L L1CaloUpgradeHistoMaker.C+ 

Create a L1CaloUpgradeHistoMaker object as follows:

L1CaloUpgradeHistoMaker myhistomaker("/path/to/my/MSU/ntupleFile.root","HistogramOutput.root")

Note: Instead of a .root file, you can also provide the constructor with a text file containing a list of paths to .root files

3) Start the event loop

myhistomaker.Loop()

Your .root file should be created.
