If you are looking for the legacy cvs LArSoft site, all content has been moved to LArSoft cvs (legacy site).

This will be the new home of the LArSoft redmine project. For the current version of this page, please visit the current wiki.


Under construction... Will go live when the migration to git/cmake is 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 FMWK framework for HEP experiments. The releases of the software are managed using an SRT distribution.

To join the LArSoft mailing list, please follow these instructions using the list name LARSOFT.

Where to find the software

At Fermilab, the software lives in a set of re-locatable ups products, each of which corresponds to the code within a git repository. Each product and associated repository contain LArSoft software components (i.e., SoftRelTool "packages") that are at a similar layer of functionality. The reference products and repository urls are the following:

repository url (all in Redmine) lxr link

larreco ssh:///cvs/projects/larreco --
larana ssh:///cvs/projects/larana --
