Challenge 4 — Design a Multimodal NeXus Application Definition

Goal

Design a custom NeXus application definition for a multimodal experiment where fluorescence and diffraction measurements are acquired simultaneously. Use this definition to convert the provided dataset into a NeXus data file. The final submission must include the application definition and the NeXus data file, uploaded to NOMAD.

What you get

  • A directory containing raw experimental data files
  • A master metadata file with scan parameters
  • A minimal ELN YAML file with partial metadata
  • A mapping template (in JSON format) showing how fields can be mapped to NeXus structure (incomplete and must be adapted)
  • You can find an example multimodal NeXus application definition below:
