cpgplot is a tool for plotting and identification of CpG islands in nucleotide sequences. The cpgplot algorithm computes CpG islands in overlapping windows along a sequence and by default defines a CpG island where the percent G + C is more than 50% and the observed vs. expected ratio is over 0.6. The minimum length of the region is 200 bases and at least 10 windows.
