Analysis of the correspondence of amino acid modelling and electron density quality in (a) Orthorhombic RNase A and (b) 3RN3 [5]. Colour codes: White = Excellent quality electron density with minimal problems for modelling a clear single conformation; Green = Clear electron density with two distinct conformations modelled; Red = Very weak or missing electron density: Blue = Disordered
