PHASER (CCP4: Supported Program)


phaser-2.7.0 - Maximum Likelihood Analysis and Phasing.




Molecular Replacement, SAD Phasing, Anisotropy Correction, Cell Content Analysis, Translational NCS/Twin Analysis, Gyration Refinement, Pruning, Single Atom MR, and SCEDS Substructure Determination/Normal Mode Perturbation of PDB files (Model Generation for Molecular Replacement).

There are some changes between this version and previous versions so input scripts may need editing.
