File Format


NeXus is developed as an international standard by scientists and programmers representing major scientific facilities in Europe, Asia, Australia, and North America in order to facilitate greater cooperation in the analysis and visualization of neutron, x-ray, and muon data.

What is NeXus?

The NeXus data format has four components:

  • A set of design principles to help people understand what is in the data files.
  • A set of data storage objects (Base Class Definitions and Application Definitions) to allow the development of portable analysis software.
  • A set of subroutines (Utilities and examples) to make it easy to read and write NeXus data files.
  • A Scientific Community to provide the scientific data, advice, and continued involvement with the NeXus standard. NeXus provides a forum for the scientific community to exchange ideas in data storage.
