The purpose of this course is to:

  • provide the attendees with an introduction to the ROOT Data Analysis Framework

  • learn the best practices of using it in the daily work

The ROOT system provides a set of object-oriented frameworks with all the functionality needed to handle and analyze large amounts of data in a very efficient way. 
Having the data defined as a set of objects, specialized storage methods are used to get direct access to the separate attributes of the selected objects, without having to touch the bulk of the data.
Included are histograming methods in an arbitrary number of dimensions, curve fitting, function evaluation, minimization, graphics and visualization classes to allow the easy setup of an analysis system that can query and process the data interactively or in batch mode, as well as a general parallel processing framework, that can considerably speed up an analysis.

Besides High Energy Physics, ROOT is also widely used in many other scientific fields, like astronomy and biology but also in finance and medicine.
