The standard Fourier Shell Correlation-based measures for resolution are generally not very reliable for negative stain reconstructions because they tend to overestimate resolution and can result in spurious values that depend on data size rather than quality, a feature that is also true for cryo-EM reconstructions (some of these issues are discussed in Subramaniam et al, Curr Opin Str. Biol 41: 194-202 (2016)). In negative stain reconstructions, we therefore use a comparison of the experimentally obtained maps with maps computed from the fitted coordinates over a range of resolutions and use this to estimate resolution conservatively. The computed maps at 20 A and 25 A are easily comparable to an experimentally obtained map, which is why we used 25 A as an estimate for resolution.
