I think there might be something going wrong with the hydrophobe feature definition, or to be more precise, with the implementation.
Using the linking amino acid Alanine as an example, the C atom will be labelled as Hydrophobe - ChainTwoWayAttach, although it is bound to the main-chain oxygen and has a negative charge. In addition, only the CA atom is identified as polar carbon, not the C bound to the oxygen. Adrian
