NetCDF (EELSlab) format#

The .nc format was the default format in HyperSpy’s predecessor, EELSLab, but it has been superseded by HSpy - HyperSpy’s HDF5 Specification in RosettaSciIO. We provide only reading capabilities but we do not support writing to this format.

Note that only NetCDF files written by EELSLab are supported.

To use this format a python netcdf interface, such as netcdf4 must be installed manually because it is not installed by default.
