Hi Gabriella,
first of all, you need to be aware of the difference between changing an assignment and changing an NmrAtom (i.e. the peak label). Changing the assignment means using a different NmrAtom/peak label for a particular peak and will only affect that peak. Changing an NmrAtom will affect your project globally and change that peak label in every place where it is used (i.e. also on other peaks and in the Chemical Shift List).
In the Peak Assigner (AP) you would change the peak assignment, by double-clicking on an NmrAtom to remove or add it to that peak’s assignments. Changing the NmrAtom would involve editing the NmrAtom, e.g. with Edit.
I’m unclear what you mean with “somehow all the atoms remained”. Which atoms remained where? Apparently in the PeakTables they did not remain? Perhaps you could explain in a bit more detail. It is unclear to me whether you were trying to change the assignment or the NmrAtoms and how the behaviour you got differed from what you were expecting.
I’m also surprised what you say about the program not being able to predict residues (amino acid types is presumably what you actually mean?). The use of HB vs. HB% etc. shouldn’t really affect this. However, we did make some changes to the amino acid type prediction a few months back, and it is possible that there could be bug in there. So it would be good to know how you changed the NmrAtoms names in an NmrResidue and how this then affected the predicted amino acid type.
Thanks,
Vicky
