h5read fails with error #12

Open schloegl opened 7 years ago

loading of hdf5 file fails with error :

x=h5read('ec013.156.nwb','/file_create_date') HDF5-DIAG: Error detected in HDF5 (1.8.13) thread 140122874586880:

I've installed hdf5oct 0.4.0 in octave 4.0.0 on linux. The file is available from here: https://portal.nersc.gov/project/crcns/download/nwb-1/hc-3/ec013.15.zip

The file can be loaded into matlab, and h5dump works also. Therefore, I'd assume it's a problem with hdf5oct.

Hello, thank you very much for reporting. I think in this case the message is expected because reading string-typed datasets has just not been implemented by anyone so far (see the ToDo section in the Readme file) probably because we have not needed it ourselves. Someone should complete it though, I agree - also because there seems to be some activity concerning the integration of hdf5oct code into octave core (see patchbay at GNU octave's savanah page). Any volunteers?
