Analytic modeling of inhomogeneous-resolution maps in cryo-electron microscopy and crystallography. 2022. IUCrJ, Vol. 9, No. 6, 728-734.<br /> <br /> == Abstract ==<br /> <br /> Refinement of macromolecular atomic models versus experimental maps in<br /> crystallography and cryo-electron microscopy is a critical step in structure<br /> solution. For an appropriate comparison, model maps should mimic the<br /> imperfections in the experimental maps, mainly atomic disorder and limited<br /> resolution, which are often inhomogeneous over the molecular region. In the<br /> suggested method, these model maps are calculated as the sum of atomic<br /> contributions expressed through a specifically designed function describing a<br /> solitary spherical wave. Thanks to this function, atomic contributions are<br /> analytically expressed through their atomic displacement parameter and local<br /> resolution, a value now associated with each atom. Such a full analytic<br /> dependence of inhomogeneous-resolution map values on model parameters<br /> permits the refinement of all of these parameters together.<br /> <br /> == Keywords ==<br /> <br /> == Links ==<br /> <br /> https://journals.iucr.org/m/issues/2022/06/00/tf5001/index.html<br /> <br /> == Related software ==<br /> <br /> == Related methods ==<br /> <br /> == Comments ==</div>
