Rescaling FSC curves. Acta Crystallographica Sec. D. 81, 11 (2025).<br /> <br /> == Abstract ==<br /> <br /> Similarity between two periodic functions is commonly assessed by comparing<br /> their Fourier coefficients within resolution shells. In particular, this approach is<br /> widely used in both crystallography and cryo-electron microscopy (cryoEM).<br /> The definition of these shells, that is the choice of resolution scale for their<br /> boundaries, can be guided by the specific goals of the analysis, by the expected<br /> features of the studied functions or simply by convention. In cryoEM, shell<br /> boundaries are traditionally defined uniformly in inverse resolution. This<br /> convention results in a vast imbalance in the number of Fourier coefficients per<br /> shell, which may bias statistical comparisons and can make function plots<br /> misleading. Constructing resolution shells with approximately equal numbers of<br /> Fourier coefficients can be achieved automatically by defining shell boundaries<br /> uniformly on the inverse cubic resolution scale. This transformation effectively<br /> zooms into the high-resolution region, which is typically the primary focus of<br /> analysis. For Fourier shell correlation (FSC) calculations between half-maps,<br /> the characteristic sigmoidal curves were observed to transform into profiles that<br /> permit piecewise linear interpolation, which may make FSC analysis more<br /> robust.<br /> <br /> == Keywords ==<br /> <br /> == Links ==<br /> <br /> https://journals.iucr.org/d/issues/2025/11/00/vo5019/index.html<br /> <br /> == Related software ==<br /> <br /> == Related methods ==<br /> <br /> == Comments ==</div>
