Figure 2.

Log-normal transform of inter-AG lengths. Inter-AG distances after log-normal transform show a roughly normal curve. To better evaluate the inter-AG distances in known trans-splicing regions, we transformed the long-tailed distribution seen in Figure 1 using a log-transform. The result is a good approximation to a normal curve, allowing us to use the full panoply of statistical analyses available for manipulations of normally distributed data.
