Which great mathematicians had great political commitments? The total size of X is 0.7GB. Similarly for HDF5, the files must be in the HDF5 format (aka NetCDF-4 format). @abe not necessarily. Opinions on NetCDF vs HDF5 for storing scientific data? netCDF version 4 has many features not found in earlier versions of the library and is implemented on top of HDF5.This module can read and write files in both the new netCDF 4 and the old netCDF 3 format, and can create files that are readable by HDF5 clients. The API is considered simpler than the HDF5 library, but in the end you have pretty much the same functionality. Please see the netCDF-Java reference docs for more details. NetCDF4 vs. HDF5 for large datasets 14 December, 2017. A Brief History of PnetCDF. I like the hierarchical aspect of HDF5 (in particular I love the directed-acyclic-graph hierarchy, much more flexible than a "regular" filesystem-like hierarchy), am reading the NetCDF docs now... if it only allows one dataset per file then it probably won't work for me. It's still in beta, but it does work and feedback is certainly appreciated! 3. It might be related to HDF5 v1.8 vs v1.10. It has one less massive binary dependency (netCDF C). Thanks for contributing an answer to Stack Overflow!
