1st Order Markov Chain Tool

Upload a FASTA sequence file to determine the probability of each letter following another. The downloaded file will contain a table of 20 probabilities formatted as follows:

Given x, P(y) =
y = A y = C y = G y = T
x = A P(A,A) P(A,C) P(A,G) P(A,T)
x = C P(C,A) P(C,C) P(C,G) P(C,T)
x = G P(G,A) P(G,C) P(G,G) P(G,T)
x = T P(T,A) P(T,C) P(T,G) P(T,T)
Start P(A) P(C) P(G) P(T)
