  1. Correlation coefficient of top forty 4-gram frequencies between Brucella suis and corresponding 4-gram frequencies in other species, computed as an average over each genera. Only genera with at least 9 species each are considered. Standard deviation also is shown. Brucella belongs to genus 1 (first row) and as seen, the correlation of 4-gram frequencies is very high at 0.99 in comparison to species of the same genera but it is lower with species in other genera whether within the same class or different class.
