If the file is corrupt, it's possible that the HDF5 library is segfaulting. You can also try reading it with the built-in Mathematica HDF5 reader. Just replace ImportHDF5 with Import. We found the built-in reader to be extremely flakey with complicated and large HDF5 files, but in simple cases it is probably fine. </div><br><blockquote type="cite"><br>B<br><br>On 12 April 2016 at 11:30, Bernard Kelly <<a href="mailto:physicsbeany@gmail.com">physicsbeany@gmail.com</a>> wrote:<br><blockquote type="cite">Hi.
