Hi Wolfram, I believe this is because Phenix (like most packages) uses a heuristic definition of "peptide" that's flexible enough to capture modified amino acids (even novel ones) - basically, anything that contains the canonical amino acid backbone (as SAM does) is captured.

Is this behavior what most users would want or even expect? Best regards.
