A. Blue bars show the frequency (count/2436) of 2436 genes in Fig. 6 by their period of oscillation in hrs.

<p>The mean period of oscillation is 24.9 hrs+/−0.09 hrs. B. Blue bars show the frequency (count/2436) of the 2436 genes displayed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003105#pone-0003105-g006" target="_blank">Fig. 6</a> by their phase φ. A phase φ of 100% corresponds to a phase of 2 π radians. The phase is also reported in hours on a separate scale. For comparison, red bars show the distribution of period and phase for <i>clock-controlled genes</i> in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003105#pone-0003105-g015" target="_blank">Fig. 15</a> as well. In Panel B the mean phase of <i>clock controlled genes</i> by functional category from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003105#pone-0003105-g015" target="_blank">Fig. 15 </a><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003105#pone.0003105-Mannhaupt1" target="_blank">[37]</a> in cycle 1 is reported in the inset. Categories are defined in the legend of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003105#pone-0003105-g015" target="_blank">Fig. 15</a>. While suggestive, an F_9,121 of 1.81 from a one-way ANOVA between MIPS functional categories is not quite significant (P = 0.07).
