Figure 13.4.6.1

The volume of the molecular mask expressed as a percentage of the volume of the p-cell asymmetric unit, as determined by the density cutoff in the h-cell. When the modulus of the density cutoff is decreased to less than the mean smeared electron density within the protein, the mask volume increases rapidly. Intersection of the tangents suggests the most appropriate density cutoff value for mask generation. [Reproduced with permission from McKenna, Xia, Willingmann, Ilag & Rossmann (1992).]
