To clarify my previous message the sequences that I am analyzing are activity states similar to those in queing theory and operations research. The data are then categorical. While methods for analyzing differences in DNA sequences exist they are far too restrictive since they deal with very few states and the rate of error is relatively small.
I use collected sequences to develop transitional probability matrices to then attempt to simulate additional sequences based on the original single step transitions. So alternatively I am exploring methods for comparing and quantifying the differences in these probability matrices. Is there a standard method or perhaps a creative and justifiable technique?
Thanks so much!

Please try to be more specific when you post a question so people in this
list can actually help you with your question. Otherwise you either don't
get a response at all or even worst, you expose yourself to be (justifiably)
"chewed out" by some people on this forum.
Cheers
