Figure 5. Probability of localizing a fusion point to an interval of a given length.

A fusion point ζ is localized to length s if the corresponding breakpoint point region Θ_ζ has length s or less. When s exceeds the clone length L, only a single clone is required to achieve this localization and consequently the probability of localization is the probability that at least one clone contains the fusion point. In the case of 1 M paired reads the 40 kb and 150 kb curves are nearly indistinguishable. Note that each curve is obtained using a fixed clone length, and that the use of a distribution of clone lengths would create a less abrupt transition.
