DireX - Tutorial
Occupancy Refinement
occ-ref-1
Flexible parts of a protein usually show reduced or even missing density in the experimental map. This effect can lead to significant distortion in the refined structure. DireX uses the occupancy refinement feature to account for reduced density which typically improves the fit. Occupancy refinement reduces the weight that each The occupancy is used as factor to the weight with which each atom contributes to the model density.
