α-coefficients of transcription factors regulating yeast metabolic cycle. A) shows all transcription factors. The 8 transcription factors in the largest cluster are represented as a single curve equal to the average of the absolute values of their α-coefficients. B) separates the transcription factor α-coefficients contributing to the averaged curve.
