Prof. R. Berríos kindly read and performed an exhaustive study of my recent article (Valenzuela, 2013) and indicated that the central column of the mutational matrix does not add up to 1, as any stochastic matrix should. I revised it with the construction algorithm and indeed it has errors. This letter corrects these errors and teaches any reader to generate and revise these matrices with the construction and correction algorithms. The column describes the probability of transformation of a

This transformation occurs after a round of duplication to 8 bacteria and reduction to 4 bacteria by random death, only by recurrent forward (A to B) and backward (B to A) mutation. Both mutation rates (and probability of mutation) are m [non-mutation then occurs with probability (1-m)].
