Example of a “comet tail” artifact in AFM images. (a) One week-old chromatin was scanned in tapping mode with a set point of ~98 % free amplitude, resulting in elongated tracks in the direction of the trace scan (left-to-right) resembling a tail of a comet. (b) Same sample as in (a) was scanned with a lower set point of ~90 % free amplitude, resulting in clear shape outlines and no “comet tail” artifact
