Towards automated crystallographic structure refinement with phenix.refine (2012, background): “Ucryst is a symmetric 3 3 matrix which models the common displacement of the crystal as a whole and some additional experimental anisotropic effects (Sheriff & Hendrickson, 1987; Usón et al., 1999).”
Averaged kick maps: less noise, more signal…and probably less bias (2009, methodology): “Crystal anisotropy can severely distort the map appearance so an anisotropic correction is typically used (Sheriff & Hendrickson, 1987; Murshudov et al., 1998; Usón et al., 1999).”
Bulk-solvent and overall scaling revisited: faster calculations, improved results (2013, methodology): “Anisotropy in the diffracted intensities is another common feature of macromolecular crystals that arises from various sources including crystal lattice vibrations (Shakked, 1983; Sheriff & Hendrickson, 1987).”
Use of TLS parameters to model anisotropic displacements in macromolecular refinement. (2001, background): “Inclusion of such anisotropic scaling is known to give improvements in crystallographic R and free R factors of up to several percent and improved behaviour of reﬁnement (Sheriff & Hendrickson, 1987; Murshudov et al. , 1998).”
Modelling dynamics in protein crystal structures by ensemble refinement (2012, unknown): “The overall model structure factors are calculated as (1), defined by Afonine et al. (2005) , incorporating overall anisotropic scaling ( Sheriff and Hendrickson, 1987 ) and bulk solvent contributions ( Jiang and Brünger, 1994 ). where, k is the overall scale factor, h is the column vector with…”
