Bar plots of the uncrossing operations involved in minimal transformations for the -sheet protein 1PKS.

<p>See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0053642#pone-0053642-g019" target="_blank">Figure 19</a> and the text for more details. Red bars: uncrossing moves; green bars: uncrossing moves; Blue bars: loop uncrossing moves; Cyan bars: elbow uncrossing moves. The same set of 195 transformations is shown in panels A and B, sorted as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0053642#pone-0053642-g019" target="_blank">Figure 19</a>. The scale bar underneath each panel indicates a distance of 100 in units of the link length.
