Comparison of metrics: (a) Number of significant clone overlaps K per clone for different cutoffs. Using liberal cutoffs P0(Snid)= 10-12, P0(Sulst)= 10-17.2, and P0(Siid)= 10-19.4 give about the same number of significant clone overlaps (~ 12.7 per clone). (b) Pr(Sulst)vs. Pr(Snid). Dots in rectangle I correspond to clone overlaps significantly relative to Pr(Sulst)= 10-17.2 but not significantly relative to Pr(Snid)= 10-12 (false positives). Dots in rectangle I correspond to clone overlaps significantly relative to Pr(Sulst)= 10-17.2 but not significantly relative to Pr(Snid)= 10-12 (false positives). Dots in rectangle IV correspond to clone overlaps significantly relative to Pr(Snid)= 10-12 but not significant relatively to Pr(Sulst)= 10-17.2 (false negatives).
