Overview of the CCP4 suite and current developments (2011, methodology): “As mentioned above, SFCHECK (Vaguine et al., 1999) provides a number of measures of data quality, but if a model is provided it will also assess the agreement of the model with the data.”
BALBES: a molecular-replacement pipeline (2007, methodology): “After the user’s input structure-factor file has been provided, it is analysed using SFCHECK and all necessary information is extracted (such as the unit-cell parameters, space group, data completeness, optimal resolution, the pseudo-translation vector if it exists, twin operators and estimates of t”
Data processing and analysis with the autoPROC toolbox (2011, unknown): “Correcting for anisotropy can be performed with SHARP (Bricogne et al. , 2003), SFCHECK (Vaguine et al. , 1999)”
PDB_REDO: constructive validation, more than just looking for errors (2012, unknown): “SFCHECK is also used to check the data completeness and to check for the presence of twinning.”
Recent developments in the CCP-EM software suite (2017, methodology): “Initially SFCHECK (Vaguine et al., 1999) analyzes the input .mrc file, followed by the main MOLREP (Vagin & Teplyakov, 2010) process and finally a third SFCHECK process comparing the fitted structure with the input map.”
A New Generation of Crystallographic Validation Tools for the Protein Data Bank (2011, methodology): “A subset of these tests is also available in other programs, such as the CCP4 (CCP4, 1994) programsTruncate (French andWilson, 1978) andSFCHECK (Vaguine et al., 1999).”
Knowledge-based real-space explorations for low-resolution structure determination. (2006, methodology): “The rmsd is within than the optical resolution (the ability to distinguish between two points in space defined as sqrt [2 (sigma_patt2 + sigma_res2)] as calculated by SFcheck, CCP4 [ Vaguine et al., 1999 ]) of the map of w2.5 A u resolution.”
