every image is average of 30 frames recorded by the direct electron detector

Helix handedness is not confirmed by sub-tomogram averaging. Used programs: BSOFT software package, particle picking by EMAN2 with e2helixboxer, 2D classification by Relion, 3D helical reconstruction by IHRSR implemented into SPIDER.
