- Are you doing sequence comparison to determine what is "highly correlated"?
- There is a lot of work in this area, much of it inspired by chromosome-
- comparison. The algorithms are still expensive (O(n*m) to compare
- two sequences of length m and n; though I think there are some good
- speed-up heuristics.)
