Thanks Mark and kallisthene. The code and table viewer you have provided work great. Many thanks.

One question however: I'm having trouble with the chunksize when using an iterator to restore the data in Python. The python error is ValueError: Shape of passed values is (1, 141887), indices imply (1, 283774)
whereas my structure is 283774 and my chuck size is 141887 (283774/2) Do I have to adjust something when creating the databuffer to get the indices to work?

Thanks,
Eben
