h5mma::mlink: Error from MathLink executable: Unsupported datatype.

[barrywardell]

Hello, I am trying to open a H5 file to load the dataset using the command:

ImportHDF5["/home/hh/Downloads/data.h5", {"Datasets", "/Trial1/Synchronous Data/Channel Data"}]

I get an error "h5mma::mlink: Error from MathLink executable: Unsupported datatype."

Attach is the file that I am trying to open.

data.h5.zip

I think the problem is that the data is array-of-double type. h5mma doesn't currently support this type of data. I think it wouldn't be too difficult to add support for this type of data.

I have committed a change [commit d21127c53c3c15d4989e008632a9f8cd1dc4d40a] which adds support for this type of data. With this version I am able to read your dataset without any problems.

Can you confirm if this works for you (if you would like a compiled version to test, tell me which operating system you are using and I will provide it)?

Great! its seems to work on Ubuntu..

I trying to compile it for MacOS X but with no luck... I am using brew to install hdf5 and szip and I cannot compile h5mma

Can you attach the compiled version to test it on the Mac?

I am sorry, when I run it in Matmatica I get

The problem with compiling appears to be a new problem since OS X Mavericks was released. I have just committed a change to the makefile which fixes it for me.

As for the binary I uploaded, I think the problem was that I had compiled and linked with a MacPorts version of gcc which you probably don't have installed. I will upload an updated binary which doesn't rely on MacPorts.

I have added support for compound datasets and checked that all datasets in the example file can now be read.

Hi

I have another issue with HDF5 file, this time there is 2 values in the array and I got this error:

In[19]:= ImportHDF5["/home/hh/Downloads/curr1.h5",{"Datasets",{"/Trial1/Synchronous Data/Channel Data"}}] During evaluation of In[19]:= h5mma::mlink: Error from MathLink executable: Unsupported datatype: Array, class 1, size 8. Out[19]= $Failed

here is the link for the file https://copy.com/ghJVx8BFczp4mSKD

The linked file doesn't appear to contain any HDF5 file. Having said that, it was clear from looking at the code that there was an error in the array reading implementation that would have caused your problem. I have committed a fix for this. I will attach an updated OS X binary for you to test.

Sorry wrong link, here is the link https://copy.com/FdyVWl0F0bnrN7mU

The error occurred in Ubuntu x64 and OS X 64 can I compile it from git?

[barrywardell]

I still don't see any HDF5 file in that one either.

You should be able to compile the latest git master branch as that already has the fix applied.

thanks

I have successfully tested that the latest master branch can load your test file. I've also committed a change which will hopefully fix the compilation issue.

I am planning to create a new release next week. This will include the Windows 64-bit version you've requested and should support array-of-double type data.

For the record, version 1.2.0 which was released 2014-12-16 contains the mentioned improvements.
