My tip for the day having been puzzled by the failure to generate a synthetic peak list that had any peaks in it from an imported SPARTA+ prediction (made simple by Gary’s nef-pipelines) is the following code for renaming HNs to Hs.
In [11]: chain = project.getByPid(“NC:A”)
In [12]: for nmrAtom in chain.nmrAtoms:
…: if (nmrAtom.name == “HN”):
…: nmrAtom.rename(“H”)
and yes, the SPARTA+ prediction was no help!
NB Luca gave a much more sophisticated version for renaming multiple atoms at once back in this thread https://forum.ccpn.ac.uk/t/backbone-assignment-predictions/28/8
