Dear Patrick,
Curerntly Analysis is not supporting DQ experiments properly. Fixing this
is on the TODO list, but not at the top right now. Clealy putting DQ
magnetisation on the axes will need special handling for both assignment
(more components to assign) and display (wht kind of axis is this).
Apart from missing special support the problem is, as you said, that you
cannot see from the sepctra that this is a DQ. All programs we know give a
fake single nucleus, some mmight even give '1H' for a 13C-13C DQ. We do not
know a good way to identify a DQ from spectral parameters.
How much one could hack with the current set-up might depend on exactly
what spectrum you have.
Sorry not to ahve better news,
Rasmus
