Hall C Software for XEM2

We are using all standard equipment and thus the standard hall C analyzer (hcana).

Sourcing our Software

Versioning

Analysis relies on CERN ROOT and HCANA as well as the mc-single-arm and other repositories. In order to maintain the newest version and work using the same software, a software directory has been made on our group disk:

• /group/c-xem2/software/
• We are currently operating with Version 1.0.0 of the XEM software package:
  • HCANA v0.90.00 (Develop 9d6b290)
  • CERN ROOT v6.22.06
  • Python v3.4.6

Sourcing Instructions

Users have access to the common users environment, and our /group/ location.

In order to source the files, simply source the setup.sh or setup.csh (depending on your shell).

You should add the sourcing of the setup script to your .cshrc or .bashrc file (depending on your shell).

Check Everything is Working

• Type python --version, and it should return the correct version
  • Make sure you can load ROOT in python (import ROOT as R)
• Open root-config --version and check the version number
• Make sure the hadd utility works
• Make sure hcana can be run from any directory. For more information on the replay and hcana, go to the REPLAY page.
  • Don't run source script in a directory that has a setup.csh script (home should be ok)
