From the two-dimensional walker diagrams, it was observed that it was possible to classify the nucleotide sequences of viruses into three types according to the diffusion coefficients. In particular, the nucleotide sequences of viruses generally have larger maximum values of the diffusion coefficients than those of the irrational or random numbers. For long sequences, this approach can be used to indicate the abundance of certain nucleotides in the sequences; but for short sequences it was difficult to distinguish a nucleotide sequence from a random-number sequence.
