[Chimera-users] Addh function and fake N, C-terminii

Hi, I want to use Addh function to add hydrogens and protonate N, C-terminii but I don't understand very well how you detect if a terminus is fake or not. For example, for the structure 3L4F, I obtain the following log : Chain-initial residues that are actual N terminii: MET 586.A, MET 586.B, MET 586.C Chain-initial residues that are not actual N terminii: GLY 652.D Chain-final residues that are actual C terminii: LEU 646.A, LEU 646.B Chain-final residues that are not actual C terminii: ASP 638.C, ARG 758.D I don't understand why GLY 652.D, ASP638.C and ARG 758.D are not terminii, can you explain me why and how the algorithm detect that ? Thank you in advance for your answer. -- Gaëlle
