1. Accepting minutes from last meeting

2. Project Status

(2-3 minutes each)

• IDR

  • Idr0071 needs more testing: Simon:

    • Imported to incorrect datasets due to

      https://github.com/ome/omero-blitz/issues/91

    • 32 images have excess metadata: Potential workaround

    • Duplicate Project/Dataset names causing issues

    • Plan to import then assess

    • Frances: plan was for prod84 (with idr0079, idr0077,

      idr0070)

    • Could release prod84 with those. Need to contact idr0071

      submitter

    • Simon - import during this week. Discuss options on Monday

• NGFF (Josh)

  • Notes from [yesterday's

    meeting</u>](https://docs.google.com/document/d/1kCTxl9LpuDjDoF4hXayahbAkR8aM2IfTbXunOCE-tJc/edit#).

    • Goal is to have masks in ome-zarr, i.e. bottom portion of:

«««< HEAD

    -   <img src="../images/2020-06-23-image1.png" alt="zarr schema" style="width:3.34896in;height:1.55926in" />

0a37477… Add alt - Simon working on spec

    -   Dundee team working on ‘bottom’ path above

    -   GS working on ‘top’ path.

    -   Omero-rois (python, OME team) used in IDR

    -   Omero-roitool (Java, GS) uses existing Java libs

-   ITK
    > [<u>inquiry</u>](https://github.com/Kitware/itk-vtk-viewer/issues/315)
    > about location of spec to add support

-   From napari zulip,
    > [<u>https://github.com/tlambert03/napari-omero</u>](https://github.com/tlambert03/napari-omero)

    -   Good to support masks

-   Discussion with Erich Bremer - Stony Brook.

    -   Mostly were discussing the intersection of RDF with binary
        > data

        -   See [<u>\[2005.06469\] Representing Whole Slide Cancer
            > Image Features with Hilbert
            > Curves</u>](https://arxiv.org/abs/2005.06469)

        -   Spatially indexed representation of polygons to overlay
            > on images

        -   Done via a column store-like representation which could
            > be used within Zarr.

        -   … &gt; Pathology … &gt; … &gt; DICOM …

    -   But: Was unclear on tile server feature. Upcoming
        > publication of one (IIF-compatible) which could be
        > submitted back. Also has an CECOG-like HTTP implementation
        > for Bio-Formats.

    -   Also, successfully using
        > [<u>native-image</u>](https://www.graalvm.org)
        > (from GraalVM) to compile Bio-Formats to native code.

        -   Doesn’t support reflection - manual effort required

    -   Awaiting publication etc.

• SA (learning/mail)

  • VMWare hypervisor and firmware updates

    • Rolling update of hypervisors, due to firmware updates will

      require VMs to be updated at our leisure (proposed timescale: over two week period following start of work by UoD IT)

    • Downtime needed. In touch with UoD IT.

  • Mail migration: Last week’s testing passed, list migration

    underway this week.

    • In retiring ome-nitpick in favor of omero-team, add Andreas,

      Emil, Wilma to latter? Maybe Kevin? Happy to go with what works for Glencoe. Current omero-team members are Chris, Melissa, Stick.

    • Chris: will discuss with GS team

• Glencoe (Chris):

  • Bioformat2raw work on Plates and Memoizer

  • n5/zarr usage in Java investigation

• Community

  • Workshop videos? July?

    • JM: video recording? Quality? zoom vs OBS etc?

    • Jason: needs discussion later

  • Community meetings? More frequent meetings suggested.
