Announcements

  • Mark announced that that we are sneaking up on making JANA 0.6.6 the official version. There have been problems getting a successful nightly build having nothing to do with the new version of JANA.
  • Elliott told us that there is a fully C++11-compliant version of gcc installed on the JLab CUE.

Standard ROOT TTree Format: TTree Format

Paul walked us through his ideas for a standard ROOT Tree format for GlueX post-reconstruction analysis. See his wiki page for details. From the first section of that page:

  • For any reaction can streamline (and provide a best-practices implementation/examples of): analysis utilities, BDT setup/input, amplitude analysis setup/input(?)
  • Makes it easy for users to keep everything organized, especially handling of the combinatoric background.
  • Output can be enabled/disabled with a single flag.
  • Format is designed to be one-size-fits-all, but is still extensible (customizable).

He noted that ROOT 5.32 or greater will be required to use this system.

A design goal is to support both direct access to variables vie TTree::Draw() and support an object-oriented programming approach to analysis under ROOT. He has had email exchanges with several collaborators to help refine his ideas.

Action Item Review

We discussed a couple of newly added issues in Mantis

  • Add thread-specific random number generators to mcsmear: reproducibility of results is not guaranteed when running mcsmear multi-threaded due to use a single random number generator, Issue 329.
  • sim-recon soft-wired for KLOE: the choice of reconstruction algorithm is done via a generic JANA configuration parameter rather than using the factory tag choice scheme, Issue 328
    • Will noted if this change is made then analysis of data challenge 1 data will require the DEFTAG parameter on the command line or in the configuration file.

Review of recent repository activity

  • David added an option to smear the beam particle momentum in genr8_2_hddm.
  • David implemented the change to geant particle numbers discussed on the email list.
