Local Error Estimates Dramatically Improve the Utility of Homology Models for Solving Crystal Structures by Molecular Replacement (2015, methodology): “…a series of cutoff values and in LLG by a smooth function deriving from the difference between the observed and calculated structure factor values in the presence of errors (Read, 1990), which does not continue to degrade once errors are large compared with the resolution of the diffraction data.”
Towards automated crystallographic structure refinement with phenix.refine (2012, background): “…Bricogne & Irwin, 1996; Murshudov et al., 1997; Adams et al., 1997; Pannu et al., 1998) the calculation of the ML target (Lunin & Urzhumtsev, 1984; Read, 1986, 1990; Lunin & Skovoroda, 1995) requires an estimation of model error parameters, which depend on the current atomic parameters and…”
Likelihood-based refinement. I. Irremovable model errors. (2002, methodology): “…a distribution, which appeared previously in a number of crystallographic applications (Luzzati, 1952; Sim, 1959; Srinivasan & Parthasarathy, 1976; Read, 1986, 1990; Lunin & Skovoroda, 1995), may be rewritten in terms of the structurefactor magnitude and phase: P F; ' F " exp ÿ F 2 Fcalc 2 " exp…”
Incorporation of prior phase information strengthens maximum-likelihood structure refinement. (1998, background): “A difference in an overall B factor corresponds to a difference in an overall Gaussian coordinate error for each partial model (Read, 1990).”
A number of real-space torsion-angle refinement techniques for proteins, nucleic acids, ligands and solvent. (2001, unknown): “A similar line of arguments could be used to show that maximum-likelihood re®nement (Lunin & Urzhumtsev, 1984; Read, 1986; Bricogne, 1988; Read, 1990; Carter et al., 1990; Murshudov et al., 1997) is similar to some extent to that of realspace re®nement (3).”

Detecting outliers in non-redundant diffraction data. (1999, methodology): “Appropriate probability distributions have been derived (Luzzati, 1952; Sim, 1959) and further generalized (Srinivasan, 1966; Read, 1990).”
Pushing the boundaries of molecular replacement with maximum likelihood. (2001, background): “This can be dealt with in the same way as positional uncertainty of individual atoms (Read, 1990) by reducing the expected value of the moleculartransform contribution and incrementing the variance correspondingly.”
