Hallo all,
I want to open a group in a hdf5 data using the H5G_open command in IDL but everytime I try I see the error message 'unable to open group: (object ID: ...., Object name: ...)'
How can I understand what is the problem wih my code?
I would appreciate any help that you can provide.
Best,
Sahar

How can I get information about the existing groups in a hdf-5/netcdf-4 data?

Have a look at the hdf5 section of my IDL library - there is a function called wmb_h5_group_exists() which tests for this.
