Ciao Ben, can you describe a bit further how your data is stored in the netcdf files? I suspect that the experimental reader is not meant to be used with your data. If your goal is to be able to read and display vector data, the easiest way is to write your own simple datastore implementation. Simone. ------------------------------------------------------- Eng.
