Hello,
Tim says:
Without 13C resonances a good prediction cannot be made! It's not our
fault. The shifts need to be added by the user. Resonances need to be put
on the intra-residue peaks and put in the same spin system as the amide.
Setting the atom type will help with the amino acid type prediction.
The prediction of inter- or intra-residue peaks is done automatically in
the automated assignment section - using the resonance setup option in the
second tab. The project should be saved before trying this. When this is
more tested this functionality will be put in a more obvious place.
