Abstract: Mathematical expressions to estimate the probabilities of rare or frequent words in genomic texts. have recently been obtained by different authors. We present a few extensions for the p-value computation, in the Markov probability model: double strand counting, some degenerated consensus. We compare with the results obtained by RSA-tools on some plant datasets. We will exhibit the co-occurrence of the G-box, the I-box and a third motif, very close the Ry-element, also called the Sph Box.
