Hi Troels, I didn't notice that the shape was not preserved. To store the numpy shape, this is also not a problem as XML has attributes. For example 'type' is the attribute already used to determine what we do with the data in relax. We simply add a new 'shape' attribute and read this then reshape when loading the data. If at any point you need help for implementing any of the XML stuff, just say and I can do a few things in your branch.
