- Next LArSoft Coordination Meeting: Tue, Jan 15, 2019

- MicroBooNE Data/Simulation Overlay Method

  - Cancelled.  Will be given on another date.

- Feature update to DetectorClocks service for data/simulation overlays

  - Proposal to add a "rebase" functionality for G4RefTime in DetectorClocks
    to support data/simulation overlays.  This allows simulated events to look
    more like real data which has a TriggerTime that runs continuously from
    the beginning of the run.

  - Implemented in a similar manner as setting of the trigger time via the
    trigger object

    - Default behavior remains unchanged.

  - This is a fundamental change of the meaning and usage of G4RefTime.  It
    must now be modified on an event-by-event basis for simulated data.

  - By doing this it is possible to match MCParticles to TPC reco objects.

  - This does not work for the BackTracker which uses SimChannel times.  Possible
    solutions are being investigated.
  
- Tools for MC truth matching

  - SBND and ICARUS use RecoUtils for backtracking events to Monte Carlo
    information.

  - Another set of functions called ShowerUtils has also been developed.

  - Both of these utilities are detector agnostic and can be used by any
    liquid argon experiment.

  - Proposal to is to move RecoUtils and ShowerUtils in a subdirectory of
    larreco/RecoAlg named MCRecoUtils.  Lynn Garren suggests lardataalg
    instead.  Wes Ketchum thinks there might be some overlap with code in
    larana.

- Event display updates

  - Cancelled, will be given on another date.
