Minutes

PC presented proposal for describing a ROI in issue #944

  • BW asks about representing a different use case where the “parent” dataset is not recorded (e.g. the detector output is limited to a subset of pixels and only this subset is recorded).

  • MK asks if this really belongs in NXdetector since it looks more like processed data than raw data

  • Would be better to be described more generally than only as a child of NXdetector

BW describes discussions with Dectris about issue #940 (summary)

  • RO likes restricting data variable labels to NX_NUMBER but is not opposed to issue #945

  • Different types of link are already allowed and their target can be discovered in HDF5. Perhaps we need to document and advertise which calls can/should be used

Draft application definition for XPCS

  • MK thinks that the variables are not very descriptive (e.g. g2), but PC says that it is standard nomenclature in the field

  • the scripts from RB could be useful to illustrate the structure of a proposed application definition

  • BW suggests that the scripts from RB could be added to the nexus_format package to make it more easily available to people planning new application definitions

  • RB will try to make his script more resilient against minor issues often found in contributed application definitions

Should we have another virtual NIAC in Spring 2022? There are plans for a hybrid NOBUGS in Autumn 2022. BW suggests encouraging more discussion on github before starting video discussions so that we can be more time-efficient.

Next meeting in mid December
