NGFF 2020 Newsfeed

Things appeared to have quieted down over the holidays, but lest the impression arise that nothing’s going on, I thought I’d post a newsfeed from my side (think: “”) to summarize recent events. If anyone else has news, questions, thoughts or ideas about the future of bio imaging formats, feel free to post below.



“ome-ngff” tag usage

Until another name solidifies, we’ll be using the #ome-ngff hashtag for updates about next generation file formats. Feel free to follow along or create new topics to ask questions.

Metadata presentations at SWAT4HCLS

@norio.kobayashi, @sukunis (in absentia), @Caterina and I presented recently at a metadata conference in Edinburgh, discussing a framework for community extensions to the metadata model. The paper should soon be included in the proceedings online, but until then, the slides are on figure.

Zarr community meetings

Though it took a few starts, the regular zarr/n5 community meetings are back on the calendar biweekly. The next call is on the 12th of February at 2000 GMT. If you have a topic to raise or would like to be added to the calendar, please speak up.

This week, Zarr’s recent membership in NumFOCUS was discussed, and both @heeler and Jackson Brown joined to discuss various use cases for converting #czi files at the Allen.

OME-TIFF Conversion tools

ICYMI: @melissa posted about a new suite of tools from Glencoe that uses zarr/n5 as an intermediate format for speeding up the transformation of proprietary file formats into pyramidal OME-TIFFs. Feedback welcome.

Multiscale arrays (i.e. pyramids) proposal

As a cross-over result from having OME & Zarr at the recent EOSS meeting along with input from @jni, @sofroniewn, and others, I’ve written up a first micro proposal (extension, specification, etc) – – for initially capturing multiscale (“pyramidal”) arrays. Feedback welcome.

Multi-scale image labels v0.1

A new specification which is the result of quiet rumblings over the summer has been published: Multi-scale image labels v0.1 which builds on top of the previous multiscale work.
