Sample predicted microtubule cytoskeleton structures and orientations.

<p>Only 24 microtubules are drawn in each computer-generated image, according to the three-dimensional shapes specified by the numerical algorithm. Top and side views of each sample structure are shown next to each other. Orientation centrosome-down is the ideal functional orientation in our plotting convention, to match our experimental setup. The number between the top and side view of the same structure corresponds to the number of the peak as labeled in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003861#pone-0003861-g003" target="_blank">Fig. 3</a>. <i>A</i> and <i>B</i>, the major type of structure predicted when there are 88 microtubules 12 µm long. <i>C</i> and <i>D</i>, the minor type of structure predicted when there are 88 microtubules 12 µm long. <i>E</i> and <i>F</i>, the dominant type of structure, when there are 300 microtubules 12 µm long. <i>G</i> and <i>H</i>, the dominant type of structure, when there are 300 microtubules 15 µm long. <i>I</i> and <i>J</i>, the minor type of structure predicted when there are 300 microtubules 18 µm long. <i>K</i> and <i>L</i>, the major type of structure predicted when there are 300 microtubules 18 µm long. <i>M</i> and <i>N</i>, the major type of structure predicted when there are 300 microtubules 9 µm long.
