ROOT

CERN maintains copies of many versions of ROOT in CVMFS. You can get the latest version as follows:

export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
alias setupATLAS='source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh'
setupATLAS

lsetup root

Alternatively, you may be able to activate root within your environment by sourcing the appropriate thisroot.sh script, for example:

source /cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.13.02/x86_64-centos7-gcc48-opt/root/bin/thisroot.sh
