NeXus exampledata

Examples of (mostly) real world NeXus files with which to inspect, test and train reading software.

This repository is organised so that files in directories called hdf4 are NeXus HDF4, hdf5 are NeXus HDF5 and xml are NeXus xml. (See a cursory critique of each file.) Note that some are broken files which are good for testing. Please advise us if you have difficulties with any of these files. For sure, we need more documentation here.

The files writer_1_3.h5 and writer_1_3__niac2014.h5 are taken directly from the NeXus online documentation

NeXus compliance of files

An automated analysis (via code critique.py) of the files, by directory, in this repository is given in file: critique. HDF5 files that satisfy the structure:

<file_root>:
    entry (NXentry)

are automatically identified as NeXus HDF5 file at this time.

An analysis by the critique.py program (in this repository) is available: critique
