Moving this discussion to the maintainers' list...Actually, zipping a HDF5 file would be not a good solution, because HDF5 already supports compressing of individual variables, including chunking and shuffling, hence more efficient. All of them is implemented in the HDF5 library - all we need is to activate it. Do you know how to do it in Octave?I don't, but I suspect it's not implemented. The src/*hdf5* files in the Octave source treeare probably the location to modify if you want to enable HDF5 compression. Perhaps something else needs to be modified elsewhere to enable an interface from the interpreter for compression. Do you need help getting started reading the Octave sources? This might help: http://hg.savannah.gnu.org/hgweb/octave/file/tip/etc/HACKING Thanks for the pointer - I'll have a look! Regards, Piotr --
