Publisher's Note: Error in Figure legend order.

Posted by PLOS_ONE_Group on 01 Feb 2013 at 22:30 GMT

The legends for figures 1 through 5 were incorrectly switched. The legend that appears with Figure 1 should be with Figure 2, and the legend that appears with Figure 2 should be with Figure 3. The legend that appears with Figure 3 should be with Figure 4, and the legend that appears with Figure 4 should be with Figure 5. The legend that appears with Figure 5 should be with Figure 1.
