In this table, AT-bias = median absolute (A-T)/(A+C+G+T). In this table, AT-skew = median absolute (A-T)/(A + T). Absolute values are used in this table to give meaning to the results for the random sample. The comparison between the actual and shuffled genomes confirms that the algorithm is finding real features in the real genome. The comparison between the actual and hybrid genome confirms that the average segment in the real genome is of stronger bias than a segment generated by transcription.
