Welcome to the ROOT Educational Resources at Fermilab

ROOT Tutorial:

Physicists are involved in the business of getting data into files, analyzing it, and then producing histogram plots and fits. This site supports our 3 day tutorial on the ROOT. The class is inteneded for the novice to intermediate user. Hopefully it will get you into using ROOT quickly.

Day 1: slides, ppt file
  • Introduction
  • GUI overview
  • Tree Viewer
  • Command line basics
  • Converting PAW files
  • Finding Information
 Day 2: slides, ppt file
  • Environment Settings
  • Command types
  • Global Variables
  • CINT Commands
  • Scripts Debugging
  • ACLiC

Day 3: slides, ppt file
  • Using Trees in Analysis
  • Add your class to ROOT
    • With the Interpreter
    • With a compiler (Shared Library)
    • With ACLiC

Examples: download all the example files used in the tutorial

Exercises: download the exercises we use in class

  • three ways you can use ROOT: the command line, the script processor, and the graphical user interface (GUI). We also show you how to generate a PostScript file.
  • histograms, and the input/output capabilities.
  • example of an analysis using real physics data.
  • example of a simulations and an event display.
