The next time you start a new session to start working, you’ll have to setup the ATLAS software environment again:
setupATLAS
Then navigate to your build directory and setup the same analysis release:
cd build
asetup --restore
source x86_64-*/setup.sh
The script will automatically setup the same release as you previously
defined in that directory. The --restore
option restores the previous setup.
See this page
for more information. Note that if you use a locally compiled
release, you should use the instructions from that
section.
And to follow this tutorial define the environment variable
ALRB_TutorialData
as explained here.
