An in-house built system was used to intercept the frames from the detector at a rate of 18 frames per second.
The particles were manually picked.

After extraction and ctf estimation of images, frames 1-32 were used for reconstruction, statistical movie processing to compensate for beam-induced movement and b-factor weighting.
