The full-symmetry TF (
Vagin, 1989) originates from the T2 function of Crowther & Blow (1967) corrected by Harada et al. (1981). It simultaneously uses all symmetry operators, resulting in a single ...

The MR method has been extended to a simultaneous search for multiple copies of the macromolecule in the unit cell (
Vagin & Teplyakov, 2000). The central point of this approach is the construction of a dimer ...
