Hi there,
I am new to CcpNmr and am trying to finish assigning resonances for a 38-AA peptide. 35 spin systems have been created already, but more are obviously required to improve the NOE constraints. I am trying to assign a backbone nitrogen (using a NOESY-HSQC overlaid onto a TOCSY-HSQC) to a new, unspecified but numbered spin system, however I am unable to rename the nitrogen and any of its associated protons as the AA residue I am assigning (e.g., Arg 591 instead of {36}). This is likely a basic question, but if anyone is able to advise I would appreciate the help.
Thanks,
E.
