Distances between the center of mass (COM) of TmAFP and its initial COM in the z-direction as a function of time.

<p>Since five simulations were performed for each force field, five values are represented with different colors, where black, red, green, blue, and yellow lines respectively correspond to systems 1, 2, 3, 4, and 5 in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0198887#pone.0198887.g002" target="_blank">Fig 2</a>.
