EM Image Reconstruction Statistics
Number of Particles 1691
Other Details THE RECONSTRUCTION WAS COMPUTED FROM 1691 DENGUE VIRUS IMAGES THAT WERE SELECTED FROM 78 MICROGRAPHS. ORIENTATIONS WERE DETERMINED BY THE MODEL-BASED POLAR-FOURIER TRANSFORM METHOD (BAKER AND CHENG, 1996, J.STRUC.BIOL. 116,120-130) AND REFINED BY THE MODEL-BASED FOURIER TRANSFORM REFINEMENT PROCEDURE(http://bond.cs.ucf.edu/ComputationalBiology/Projects/POR/Home.html).
