Consecutive images from an HS-AFM video depicting S trimer in various states, as indicated in the bottom left corner of the images. The white arrowhead indicates the stalk region of the spike, while the yellow arrowheads indicate the opening of RBDs. The acquisition rate of the video was 2.5 fps. These images were processed with a set of user-written macros (see Methods).
