Hi,

When I use

h5read('wo.h5',,'/g4/lat'),

got some errors as below: Error using h5readc The HDF5 library encountered an error and produced the following stack trace information:

    H5G_traverse_real    component not found
    H5G_traverse         internal path traversal failed
    H5G_loc_find         can't find object
    H5Dopen2             not found

Error in h5read (line 58) [data,var_class] = h5readc(Filename,Dataset,start,count,stride)

I am using Matlab 2013b, Does it matter with this? Thanks for help.

There is a typo, two commas where there should be one.
The reason to the error is most likely that '/g4/lat' doesn't exist in your file. A typo?

I have found the program HDF5View very useful when working with HDF5-files. See HDF5 Tutorial: Learning HDF5 with HDFView

Agree, the error messages could have been more user friendly.

A little test with R2013a. The dataset, '/g4/lat', does not exist in 'myh5file.h5'. I get the same error message as you did.

    >> h5read('myh5file.h5',,'/g4/lat')
     h5read('myh5file.h5',,'/g4/lat')
                          |
    Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.
    >> h5read('myh5file.h5','/g4/lat')
