News / Meetings / Visitors

  • "How to Use git" talk Tuesday 9 am MT/11 am ET
  • Ville will give a CASA Developers Talk in late February on Using BitBucket and Bamboo.

Test Failures

  • 8420_Sim_Testcomp, 8411_Sim_M51C -- Remy Indebetouw

These tests can be run with e.g.
  • casa --nologger --log2term -c `echo $CASAPATH | awk '{print $1}'`/gcwrap/python/scripts/regressions/admin/ ic2233

Build, Release

  • 4.7.1 release
    • ALMA Pipeline is about to merge. We will begin testing and packaging.
    • There may be some confusion about where we are on this release. Jen will discuss with John and get back to Jeff.
    • Know issues: Changes to spectral index
  • Ville will remove failing test from 4.7.1 release. (sim orion mosaic)

Verification Testing

  • Last week Akeem supported clean up of test failures.
  • Hardware order to get additional machines (4 Mac minis and a linux VM host) has been made
  • Update to plone test framework document is top priority

Validation Testing

  • plone testing being split into two stages -- if you have not yet submitted your content, please do!
  • CAS-9232 testing scope
  • George -- is Feb 1 still the anticipated date after which all of the VI/VB2 changes will be submitted and ready for testing?
  • final move to git system with start of 5.1? (just confirming)
    • When we branch for 5.0, Jeff will ask everyone to begin using the new workflow. Will continue svn workflow for 5.0 release.



  • CAS-9426 (MPI get filtered casa dict) fixed, CAS-9287 (Open MPI 2.0.1) investigation
  • Run the ALMA pipeline with the latest casa tarballs in parallel with different datasets, but they all fail due to a missing PB file in the Minor Cycle. There is a warning earlier of a copying failure: WARNING: Exception copying /data/nas2/users/scastro/casa/pipeline/cas9519/run/oussid.s28_0.J03324-2800_sci.spw17.mfs.I.iter0.pb: [Errno 2] No such file or directory: '/data/nas2/users/scastro/casa/pipeline/cas9519/run/oussid.s28_0.J03324-2800_sci.spw17.mfs.I.iter0.n2.pb. I have discussed it a bit with Dirk Muders, but no conclusion yet.
  • Have started a new batch of tests in parallel, but only using the calibration pipeline on several datasets. They all pass successfully.


  • plotcal and plotants GUIs don't work with new startup/3rd-party packages
  • CASA Docs (Plone)
    • First drafts were due Jan 13th. Please prioritize completion of any remaining assignments. You can view your assignments here: My Plone Tasks
    • Document review will begin this week. Will take part in 2 sequential stages:
      • "Verification" will address styling rules
      • "Validation" will address document content
    • Reviewers will make minor changes directly to document. Extensive changes will be returned to developers via the applicable JIRA ticket.
    • How will we deal with CASA Core documentation such as MSSelection?
      • Not much change is happening in CASA Core documentation from outside our team.
      • Kumar reports there is a more updated LEL document on a Dutch web site.
      • We can either incorporate CASA Core documentation into plone or link to a PDF.
      • Urvashi asked for guidance on styling.
        • Styling will mostly be handled by the verification team, but Anand, Juergen, and Jen will discuss Urvashi's question later this week and respond to her.
      • George asked how we will maintain selection documentation that is pertinent to many tasks.
        • We will put selection syntax in data selection chapter and link to this from task pages.
  • Development Process


  • Percentage of ALMA calibration pipeline runs sent to manual reduction decreased significantly from Cycle 3 to Cycle 4
  • ALMA Cycle 5 representative source imaging support issues resolved, required information will be in the SBSummary table
  • ALMA archive support required for Cycle 5 lifecycle changes and pipeline restore operations
  • Identified some CASA version handling issues


  • (Qn from UR) : How about a CASA-staff page as part of our new documentation tree ? In its simplest form it can contain an alphabetical list of all our names, each with a paragraph of text. Each person can choose what to and what not to put on there - background, research interests, role in CASA, link to homepage, etc. I found the introduction emails that Federico and Enrique sent out recently to be very useful and it made me realize that a lot of us probably have no idea about the range of experience/expertise others on the team have since we see only the narrow bit that each one is actively working on. And, off course, Federico and Enrique - Welcome !
