Comparison of the distributions of the island length for both the CpGcluster and Takai/Jones algorithm (top left); the observed to expected ratios of CpG frequencies (top right); the island GC-content (bottom left); and the island CpG density (bottom right). It can be seen that, for all this four properties, the SWA distributions are heavily biased towards their respective thresholds. However, CpGcluster distributions do not show this artifact.
