CpG Islands. CpG Islands searches for CpG islands in a DNA sequence using the method described by Gardiner-Garden and Frommer (1987). The calculation is performed using a 200 bp window moving across the sequence at 1 bp intervals. CpG islands are defined as sequence ranges that give a y-value of greater than 0.6 and a GC content of greater than 50%.
