I can see the file structure OK in HDFview 3/.1 but when I try to look at the data I get the following message:
An error occurred while loading data for the table:
Failed to read scalar dataset:Can’t open directory or file.
The data is Chunked in quite large sizes 8192 X 1 or 4096 X 1.
Regards,
Rob
Rob, can you send us the output of h5dump -pBH <your file>? What’s your OS? Maybe there’s a dangling reference via an external link. G.
Hi Gerd,
Thank you for your reply. I am using windows 10. I cannot look at any data no matter how small the sample I would like to see is.
Here is the dump. I have put 1/2 in as the file became too large and will send the rest in another email just in case you need it.
regards,
Rob

The file appears to be a PyTables file, created by pandas. (?) Did you create the file locally, or did you get it from someone else? The datasets appear to be (chunked and) compressed with BLOSC. If HDFView can’t access the BLOSC filter, you’d see an error message like the one you are seeing. The HDF5 library (included in HDFView) will be looking for it in default places, but you can help by setting the HDF5_PLUGIN_PATH variable to the directory where you keep a copy of the BLOSC DLL. You can get the plugins from https://www.hdfgroup.org/downloads/hdf5/ (see under “Filter Plugins (Encode and Decode)”). See also https://www.hdfgroup.org/2018/06/hdf5-or-how-i-learned-to-love-data-compression-and-partial-i-o/ for some related material.
HI Gerd,
Thank you for your reply. I did not make the data set which I think is why I cannot read it.
I do not think I had the the BLOSC filter as I did not have the plugins loaded and I have now done this and I can see the BLOSC files now in “C:\Program Files\HDF_Group\HDF5\1.10.6\lib\plugin” and “C:\Program Files\HDF_Group\HDF5\1.10.6\HDFPLExamples\example\testfiles”.
However HDF5 still produces the same error.
I do not know how to use the “set the HDF5_PLUGIN_PATH variable” command as HDFview may still not know where the BLOSC DLL is.
Regards,
Rob
How about https://www.computerhope.com/issues/ch000549.htm ?
Just create a user variable HDF5_PLUGIN_PATH and set the value to C:\Program Files\HDF_Group\HDF5\1.10.6\lib\plugin?
If you are familiar w/ Python/pandas you should be able to access the data w/o HDFView.

Hi Gerd,
Thank you very much.
he new path in environment variables worked so HDFviewer worked and I can export the files to read in Octave (at present as I maybe able to use Matlab too). .
Regards,
Rob
