I have been trying to add a residue to my model in coot for hours now.  The add terminal residue function adds a residue far from the end of my chain and I've tried moving it manually and it keeps going back and it never makes a bond between the two amino acids.  Is there a trick in coot or a better way to do this in phenix?  

Thanks,
