Hello, I've just run the Structure comparison tool for the first time using phenix 1.9-1692. All the results tabs--except the Ramachandran tab--have per-residue values throughout the length of the ~450-residue sequence; the Ramachandran tab has values only through residue 429. The sequence file included with the run contains 453 residues. Each of the pdb files input to the run have between 445 and 450 residues each. Throughout the length of each model, all models are 100% sequence-identical to each other and to the sequence file. Is it a known bug, that the Ramachandran values are not output for all the residues for which there are values in the other tabs?
