The program is intended to search for CpG islands in sequences.

Output example:

Search parameters:  len: 200   %GC: 50.0   CpG number: 0   P(CpG)/exp: 0.600   extend island: no   A: 21   B: -2
Locus name:  9003..16734 note="CpG_island (%GC=65.4, o/e=0.70, #CpGs=577)"
Locus reference:   expected P(CpG): 0.086   length: 25020
    20.1%(a)  29.9%(c)  28.6%(g)  21.4%(t)   0.0%(other)
