Wiki for the legacy cvs-based LArSoft project

[[larsoftsvn:| Wiki for the legacy svn-based LArSoft project]]


As of Jan 24, 2014, LArSoft has transitioned from svn / SRT to git / mrb / ups. These pages will be in flux for the next week or so until the documentation updates are completed.

The LArSoft software is designed to work for all planned and running liquid argon experiments at Fermilab. It is written in C++ and built on the ROOT data analysis software, and the art analysis framework supported by the Fermilab Scientific Computing Division for intensity frontier experiments.


  • Fermilab computing accounts: see the [[larsoftsvn:Fermilab Computing Access]] page if you need an account.
  • See [[larsoftsvn:Load Balanced Access to General Purpose VMs]] for information on accessing experiment VMs at Fermilab (e.g., lbnegpvm0X, uboonegpvm0X, etc., collectively known as GPCF.).
  • See the documentation section below for information on working with LArSoft, and using git, git flow, mrb and other tools you will need.

Working with LArSoft

Links to the tools used to work with the software

git and git flow:
  • git flow quick start (edited 2/4/2013).
  • Git Tips and Tricks (Note that "git help" works, but "man git" and "git help <command>" does not on any of the gpvm machines. Nor do any of the "git <command> -h" commands.) For the purposes of LArSoft development, please please ignore the workflow advice as anything other than an example of how to use various git commands to do specific tasks.
Understanding CMakeLists.txt and product_deps files mrb and ups:
  • mrb : the multi-repository build tool
  • Re-locatable ups
  • About qualifiers: the things after "-q" in setup <prod> <ver> -q <qual>
