WebRemark on using amplitudes (Fobs) vs intensities (Iobs) Although phenix.refine will read both data types, intensities or amplitudes, internally it uses amplitudes in nearly all calculations. Intensities are converted into amplitudes using French&Wilson method. phenix.refine organization A phenix.refine refinement run always consists of three steps: WebObserved structure factor amplitudes, Fobs. FC Calculated structure factor amplitudes, Fcalc. PHI Phases, Phi. SCALE (Compulsory.) and are scale factors for Fobs and Fcalc respectively. For example, = 2.0 and = -1.0 allows one to calculate a 2FO-FC omit-map.

WebA good MAD solution will typically have an FOM greater than 0.4, while a SAD solution should usually be greater than 0.3. F (model): the structure factors calculated from the model, which in this context also includes the bulk-solvent contribution. Sometimes also referred to as "F (calc)". F (obs): experimentally observed amplitudes. WebSFCHECK produces the so called total omit map by an automatic procedure. First, the initial (Fobs, PHImodel) map is divided into N boxes. For each box, the electron density in it is … eagle center winona mn
