(Top) Some of the STEM DF images from the tilt-series.
The tilt angle is reported for each projection, being the electron beam perpendicular to the specimen at 0°. The z-axis corresponds to the direction of the electron beam for the reconstructed tomogram. (Bottom). A view rotated by an angle of 20° around the horizontal x- axis of the tomogram of the collagen bundle refined by CS. The typical striation for the collagen fibrils is visible indicating that an appropriate resolution was achieved.
