How to Run CERN ROOT

ROOT is an object-oriented program and library developed by CERN. It is a framework for data processing. “It was originally designed for particle physics data analysis and contains several features specific to this field, but it is also used in other applications such as astronomy and data mining.”http://en.wikipedia.org/wiki/ROOT (27 June 2011)

root

To exit the cint C++ interpreter, at the root prompt, enter: .q

Available versions of ROOT

To discover what versions of ROOT are available, at the shell prompt, enter:

module avail cern_root

To use a version other than the default production version, at the compute node shell prompt, enter:

module load cern_root/5.26.00
