The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Towards automated crystallographic structure refinement with phenix.refine (2012, background): “…(RSR) of coordinates has a long history (Diamond, 1971; Deisenhofer et al., 1985; Urzhumtsev, Lunin & Vernoslova, 1989; Jones et al., 1991; Oldfield, 2001; Chapman, 1995; see also the discussion of and references to earlier original works in Murshudov et al., 1997; Korostelev et al., 2002).”
Real-space refinement in PHENIX for cryo-EM and crystallography (2018, methodology): “…from the atomic model directly as a sum of individual contributions of M atoms with each contribution being a Fourier image (or its approximation) of the corresponding atom at a given resolution (e.g. Diamond, 1971; Lunin & Urzhumtsev, 1984; Chapman, 1995; Mooij et al., 2006; Sorzano et al., 2015).”
Simulated-annealing real-space refinement as a tool in model building. (2002, methodology): “They were the ®rst to use a model electron-density function that explicitly accounts for the resolution limits (Chapman, 1995).”
New tools for the analysis and validation of cryo-EM maps and atomic models (2018, methodology): “Also, there exist other approaches to obtaining a map from a model (e.g., Diamond, 1971; Chapman, 1995; Sorzano et al., 2015).”
