In these examples a simple analysis of files containing data from the CMS experiment (partly simulated) is performed.

Data files

Some examples use ROOT to produce histograms.

Simple ROOT example

To activate ROOT in LabP036 room (ubuntu_old only):

source /opt/root.cern.ch_v5.34.10/bin/thisroot.sh or source /opt/root.cern.ch_v5.34.10/bin/thisroot.csh
