Fobs vs fcalc plot

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.

WebFor an Fobs - Fcalc map calculation the scales of FOBS and FCALC amplitudes need to be set to one. Also here SCALE FCALC means that FCALC should be scaled in accordance with the last R-VALUE calculation. > reflect set ampl phase fwork = fcalc * 1. > reflect set ampl scale fcalc fwork = fobs * 1. - fcalc * 1. A Patterson Fobs map requires only a ... WebAbsorption is the fact that the intensities of the measured reflections are reduced because the diffracted beams are absorbed when travelling through the crystal. If our crystal was a perfect sphere, then this wouldn’t matter: All diffracted beams will have to travel through the same length through the crystal (assuming that diffraction ...

WebNote that the indices do not count as columns so if your file contains H K L Fobs Sigma, then Fobs is column 1. SFTOOLS can also read, write, and create density maps. Maps are stored at the end of the REF array whereas reflections are stored at the beginning. The size of the REF array is determined by parameter MAXDAT in the sftools.inc file.
