NeXus File Layout#
SPEC data files contain data from one or more measurements called scans written according to the Standard Data-File Format. 1 Each scan is numbered (where the number is not necessarily unique within a data file). NeXus files are written 2 as HDF5 files with a tree structure 3 where the groups use the NeXus base class 4 definitions.
HDF5 files are binary (not human readable); in this documentation, the tree structure (hierarchy) of the file will be shown. Various terms are shown symbolically, as described in the next table.
