Project status report [Gianluca Petrillo]

  • Working with 5.0.1 version of clang; final goal is to support OSX again, plan is to make it work on Linux platform first
  • LArSoft recommends the use of CVMFS.
  • Problems with the CVMFS server overload on Mac OS are not known to be solved yet

Conclusions

  • CVMFS: need sign off from the experiments as old area will be not available after April 10

Changes in LArPandoraContent v3.11 [Andrew Smith]

  • adding neutrino identification
  • zero or one neutrino interactions are identified
  • Particle stitching between multiple drift volume only affect detectors with multiple drift volumes
  • feature/larpandoracontent_v03_11_00, affected repos: larpandoracontent, uboonedata, uboonecode
  • [Giuseppe] where is stitching code?
  • [Gianluca] can it be extended to identify more than one neutrino interaction? [A] Yes, each interaction ("slice") is assigned a score, it's just matter of selecting slices with highest scores
  • [Giuseppe] the score should be persisted, and quantities used for it as well [A] that is a feature we want and we should contact LArSoft to start that if MicroBooNE is interested
  • [Lynn] is MicroBooNE ok with this new update going in LArSoft? [Herbert] yes

Conclusions

  • given the interest by MicroBooNE in persisting the score, the Pandora group will advance a proposal

Storing the initial tick of TPC waveform in raw::RawDigit [Gianluca Petrillo]

  • proposal to add a new data member to raw::RawDigit to allow more robust procedure to truncate the waveforms

Conclusions

  • MicroBooNE accepts the proposal
  • e-mail follow up to inform the stakeholders not present in this meeting
