      Review of minutes from the last meeting

We went over the minutes from the April 23rd meeting 
The only point discussed was the future of these meetings. We agreed 
that they should go on with pretty much the same frequency and pretty 
much the same set of topics as they have in the past. Stay the course!

      Issues on GitHub

We went over issued for HDGeant4 

  * Segfault <https://github.com/JeffersonLab/HDGeant4/issues/110> #110
    opened 7 days ago by nsjarvis
  * G4Exception crash after Curve length mis-match
    <https://github.com/JeffersonLab/HDGeant4/issues/109> #109 opened 25

  * Crash after GetHadronicInteraction no model found
    <https://github.com/JeffersonLab/HDGeant4/issues/108> #108 opened 25

      o There is a suspicion that these three issues are related to the
        version of geometry being used. We will follow up with nsjarvis.
  * Feature request - progress indicator
    <https://github.com/JeffersonLab/HDGeant4/issues/107> #107 opened 27

      o We agreed that the classic HDGeant logarithmic event count
        report would be good for HDGeant4 as well.
  * Reading in # events and source
    <https://github.com/JeffersonLab/HDGeant4/issues/105> #105 opened on
    Apr 19 by nsjarvis
  * Run number read in from two places is confusing
    <https://github.com/JeffersonLab/HDGeant4/issues/104> #104 opened on
    Apr 19 by nsjarvis
  * Skip (in control.in) is ignored
    <https://github.com/JeffersonLab/HDGeant4/issues/103> #103 opened on

  * Terminal cleanup?
    <https://github.com/JeffersonLab/HDGeant4/issues/102> #102 opened on

      o These four issues were discussed at the last meeting. We have a
        plan for their resolution.
  * Calorimeter timing mismatch between g3 and g4
    <https://github.com/JeffersonLab/HDGeant4/issues/93> #93 opened on

      o Richard pointed out the mcsmear is not operating on the
        recommended HDDM elements being output by HDGeant4 for BCAL
        energy. Until that change is made, comparisons can only be done
        with obsolete quantities. He will make the change in mcsmear and
        will push it as a new branch of halld_sim. Alex and others can
        then use the branch to repeat their studies.
  * Hit Energy Agreement
    <https://github.com/JeffersonLab/HDGeant4/issues/89> #89 opened on
    Feb 26 by ReBarsotti
      o This issue is on hold until studies can be repeated with the
        latest software.

      Possible Issues from the Collaboration Meeting

We discussed various plots shown and talks given at last week's 
Collaboration Meeting and MC Comparison Workshop 

  * In Colin Gleason's talk on ηπ he showed acceptance vs. cosθ_GJ for
    both G3 and G4. Differences were significant.
  * Mark's Software Talk, he showed a plot from Peter Pauli showing β
    vs. p for K^− 's where there were large differences between G3 and G4.
  * Many of the talks in the Workshop on Comparison of Data and Monte
    Carlo showed G3 and G4 comparisons.

We agreed to turn these into issues on hdgeant4 GitHub site. For the 
talks at the Workshop we assigned an ambassador to each of the speakers 
charged with contacting the speaker to see if they have relevant issues:

Speaker 	Ambassador
Mark Dalton 	Sean
Simon Taylor 	Simon
Amy Schertz 	Justin
Naomi Jarvis 	Mark
Sean Dobbs 	Sean
