I'm refining a structure ( at low res ), so I trimmed off all the side chain atoms from my model while my reference model still has these chains. I'm receiving errors like... ----------Correcting rotamer outliers to match reference model---------- ** evaluating rotamers for working model ** A 502 ILE is missing some sidechain atoms, **skipping** A 504 LYS is missing some sidechain atoms, **skipping** A 505 VAL is missing some sidechain atoms, **skipping** I don't care about the side chain atoms, but I'd still like the reference model restraints to provide secondary structure. Does "**skipping**" mean that the reference model is no longer being considered for the particular residue? Or will I still retain my secondary structure from the reference model?
