Attribute error in NmrAtom


I have a problem when double-clicking in an @NmrResidue in the Backbone Assignment module. In most of @NmrResidues, it appears this error so I cannot do the assignment automatically. May you t know why this may be due to? Many thanks

Hi Martí,
it isn`t immediately obvious what is causing this error. I think the best thing might be if you send me your project ( and I`ll take a look at what is going on.
Best wishes,
