Determination of particle orientation and center parameters and subsequent 3D reconstruction were carried out using programs in the IMIRS software package, which are based on Fourier common lines and Fourier-Bessel synthesis methods. Prior to the merging of particles for 3D reconstruction, the Fourier transform values of individual images were corrected for the CTF with 15 percent amplitude contrast and a decay factor of 35 sq. Angstroms.
