Setting up ROOT
(5 minutes)
Before you start using ROOT, you often have to set it up:
If you’re not using one of the Nevis particle-physics systems, hopefully you have received instructions on how to set up ROOT at your site. Now is the time to follow those directions.
If you had to install ROOT on your own you already know whatever special set-up you need on your local computer.
If you are using one of the particle-physics systems at Nevis, no special set-up is needed.
Nevis specifics
There’s an alternative distribution of the ROOT software on the Nevis particle-physics systems that’s available with this command:
conda activate /usr/nevis/conda/root
This modifies your UNIX environment to use a more full-featured ROOT setup than I was able to install natively on our standard Linux installations. If you have difficulty running ROOT on your workgroup’s server, you may to try that conda command.
Working-group specifics
Even at Nevis, some physics groups work with software frameworks that have their own versions of ROOT built-in; e.g., Athena in ATLAS or LArSoft in MicroBooNE. If you’re working with such a framework, you’ll have a special set-up command to use.
