Hi Hortense,
I haven't worked with multi channel images yet, but why do you want to
copy one channel that is contained in your multi channel image and place
it to a child node of that multi channel image in the first place?
I would assume, that you need to deep-copy the data in the channel to a
separate mitk::Image and then you can add it to the new node.
Best,
Ingmar
