WebHigh-resolution 3D refinement¶. Once a subset of sufficient homogeneity has been selected, one may use the 3D auto-refine procedure in relion to refine this subset to high resolution in a fully automated manner. This procedure employs the so-called gold-standard way to calculate Fourier Shell Correlation (FSC) from independently refined half … WebMar 2, 2024 · 3D Flexible Refinement (3DFlex) (Beta) is a motion-based deep generative model for continuous heterogeneity.It can model non-rigid motion and flexibility of a protein molecule across its conformational landscape, and can use the motion model to combine signal from particle images in different conformations to improve refinement resolution in …
