Assigning resonance type in backbone assignment

I want to assign the resonance type in backbone assignment, but when I double click on the type box for an assigned peak nothing happens. Is there a trick to being able to define the residue type? Thanks!


I`m unsure where (and why) you are trying to double-click. Are you using the Peak Assigner module? Either use the drop-down menu to select your Amino Acid type, or simply click once and type something.

Best wishes,
