3D Reconstruction
Reconstruction Method SINGLE PARTICLE
Number of Particles 1455
Reported Resolution (Å) 30.0
Resolution Method FSC 0.5 CUT-OFF
Other Details Initial reconstructions were determined from a side-view 2D average based on observed 7-fold symmetry of the top view using a rotational extrusion method. The initial model was then refined in 6 iterations with EMAN2 using untilted particles. (Single particle--Applied symmetry: C7)
