CorGen is a web-based tool to measure long-range correlations in DNA sequences characterized by a power-law decay of the autocorrelation function of the GC-content. CorGen also has a function that generates random DNA sequences with user-specified parameters, alternatively by using the parameters obtained from another DNA sequence.
