                <details>Regarding negative occupancies: 
To assess fit-to-density, we derived cross-correlations at the amino acid level and by means of a map/model FSC. To perform this assessment, we generated a weighted map, derived solely from an atomic model that accounted for both ADP of all atoms and weak/negative density of all charged oxygen atoms, and compared it with the experimental map. The weighted map provides a better approximation of the experimental map by simulating map variability as opposed to treating all atoms equally. The correlations for both the FSC and the per-residue assessment showed improvements when properly weighted, further demonstrating that our model provides a good approximation of the experimental data</details>
