3D Reconstruction
Reconstruction Method SINGLE PARTICLE
Number of Particles 117012
Reported Resolution (Å) 3.1
Resolution Method FSC 0.143 CUT-OFF
Other Details Asymmetric reconstruction without alignment was performed on each of two subsets (randomly assigned) from an ACP domain density-containing class after focussed 3D classification. This led to the generation of two half-maps, which were used to generate a sharpened map from all the data. Note that the number of particles given above includes particles contributing to multiple symmetrically redundant orientations, as particles were generated through focussed 3D classification.
