Program VUE: analysing distributions of cryo-EM projections using uniform spherical grids. 2024. J. Applied Crystallography, Vol. 57, p. 865-876<br /> <br /> == Abstract ==<br /> <br /> Three-dimensional cryo electron microscopy reconstructions are obtained by<br /> extracting information from a large number of projections of the object. These<br /> projections correspond to different ‘views’ or ‘orientations’, i.e. directions in<br /> which these projections show the reconstructed object. Uneven distribution of<br /> these views and the presence of dominating preferred orientations may distort<br /> the reconstructed spatial images. This work describes the program VUE (views<br /> on uniform grids for cryo electron microscopy), designed to study such distributions.<br /> Its algorithms, based on uniform virtual grids on a sphere, allow an easy<br /> calculation and accurate quantitative analysis of the frequency distribution of<br /> the views. The key computational element is the Lambert azimuthal equal-area<br /> projection of a spherical uniform grid onto a disc. This projection keeps the<br /> surface area constant and represents the frequency distribution with no visual<br /> bias. Since it has multiple tunable parameters, the program is easily adaptable to<br /> individual needs, and to the features of a particular project or of the figure to be<br /> produced. It can help identify problems related to an uneven distribution of<br /> views. Optionally, it can modify the list of projections, distributing the views<br /> more uniformly. The program can also be used as a teaching tool.<br /> <br /> == Keywords ==<br /> <br /> == Links ==<br /> <br /> https://journals.iucr.org/j/issues/2024/03/00/yr5116/yr5116.pdf<br /> <br /> == Related software ==<br /> <br /> == Related methods ==<br /> <br /> == Comments ==</div>
