Before revision:  We present a protocol for Enumerative Real-space Refinement ASsisted by Electron density under Rosetta (ERRASER), coupled to PHENIX diffraction-based refinement.
After revision:  We present a protocol for Enumerative Real-space Refinement ASsisted by Electron density under Rosetta (ERRASER), coupled to Python-based hierarchical environment for integrated 'xtallography' (PHENIX) diffraction-based refinement.
