   I'm trying to run some simulations using kspaceFirstOrder3D-OMP, but am having some problems with the HDF5 libraries.

   Here's the text of the error using a binary I compiled under Mac OS X 10.9.3 using icc and MKL:

   --------------------------------
     kspaceFirstOrder3D-OMP v1.0
   --------------------------------
   HDF5-DIAG: Error detected in HDF5 (1.8.12) thread 0:
     #000: H5A.c line 557 in H5Aopen(): unable to load attribute info from object header for attribute: 'file_type'
       major: Attribute
       minor: Unable to initialize object
     #001: H5Oattribute.c line 537 in H5O_attr_open_by_name(): can't locate attribute: 'file_type'
       major: Attribute
       minor: Object not found
   libc++abi.dylib: terminating with uncaught exception of type std::__1::ios_base::failure: Error: Could not read from "file_type" attribute of "/" dataset!
   : unspecified iostream_category error
   Abort trap: 6

   And here's the text of the error using the pre-compiled binary from k-wave.org on Ubuntu 12.04

   --------------------------------
     kspaceFirstOrder3D-OMP v1.0
   --------------------------------
   HDF5-DIAG: Error detected in HDF5 (1.8.7) thread 0:

     what():  Error: Could not read from "file_type" attribute of "/" dataset!
   
   Aborted (core dumped)

   I think the problem is with the HDF5 input file being created with kspaceFirstOrder3d in Matlab (R2013a 8.1.0.604). I'm just using the IVP photo acoustic waveform example to test if the C++ code is working and compare against the Matlab output. The HDF5 input file I'm using is available here: https://www.dropbox.com/s/ksgtgkkgt3qfuws/photoacousticWaveform3D.h5

   Any ideas on what could be causing this or a possible solution? I'm contemplating writing my own function to generate the input file since I need to run fairly large domains (~10 cm largest dimension for a 10 MHz transducer) for the applications I'm working on.

   thanks for any ideas,

   Turns out it was Matlab related. It appears there are problems with HDF5 file writing for r2013a (at least on a Mac). I generated a new HDF5 input file with r2012b (also on a Mac) and it worked one with the Linux binary on Ubuntu 12.04.

   Hi PJ,

   Thanks for the feedback - that's helpful. We will try and get to the bottom of the what's happening in R2013a.

   Brad,
   No problem. Here's a link to the r2012b HDF5 file just in case it's helpful: https://www.dropbox.com/s/hccmbzllbgal10k/photoacousticWaveform3D_r2012b.h5
