MATLAB: Hdf5 file read problem.

hdf5

Hi, I have a series of cgns files which I want to process in Matlab. I use a command of cgnstools in linux named adf2hdf and also cgnsconvert to convert the cgns files into hdf5 files. I can get the structures with h5info and h5disp, but when I want to use h5read it complains with following error:
 Error using h5readc
 The HDF5 library encountered an error and produced the following stack trace information:
    H5Dopen2    not a dataset
 Error in h5read (line 59)
 [data,var_class] = h5readc(Filename,Dataset,start,count,stride);
A sample file has been attached. I had to change the extension to png so I can upload it. After download you can change it back to hdf5 but it doesn't really matter for Matlab.

I would call this a practical joke. There is a leading space in the names of the datasets. (Caveat: This is the first time I encounter the CFD General Notation System.)
You didn't tell what you tried to read, however, try
>> num = h5read( 'h:\m\cssm\xy.h5', '/ format' )'
num =
   73   69   69   69   95   76   73   84   84   76   69   95   51   50    0
and
>> num = h5read( 'h:\m\cssm\xy.h5', '/xyplane/sidesplane/ZoneType/ data' )'
num =
   85  110  115  116  114  117   99  116  117  114  101  100
