This lesson requires several software packages common in high-energy physics. This exercise is intended to be used for Fermilab’s CMS Data Analysis School 2025. If you have completed the pre-exercises, go to the following CMSSW area and set the CMS environment to access these packages.

Connect to the LPC cluster:

BASH

kinit <YourUsername>@FNAL.GOV               # if needed
ssh -XY <your-username>@cmslpc-el8.fnal.gov

Access your CMSSW environment:

BASH

cd ~/nobackup/cmsdas/CMSSW_13_0_10
cmsenv
mkdir root-exercise
cd root-exercise/

Now you are ready to do the steps of this exercise in your terminal!
