C3 15.0 OTHER motioncorr, IMOD, TomoCTF, PEET, bsoft
Images were aligned using motioncorr. Tomograms were reconstructed using weighted back projection. CTF correction was performed employing TomoCTF. PEET was used for the generation of the subtomogram average. Bsoft was used for the generation of the mask, application of mask, application of symmetry and FSC determination.
