(a) A color screenshot from our software displaying inferred profiles of 5 significant processes for the H₂O₂ experiment. Red represents induced activity, green repressed activity and black no change. The 5 processes are (from top to bottom): response to oxidative stress; ubiquitin-dependent protein catabolism; chromatin silencing; ribosome biogenesis and G1/S transition of mitotic cell cycle. (b) Squared error for reconstructed gene expressions as a function of the number of processes kept. (c) Budding index counts. The percentage of “G1”, “S” and “G2/M” cells are plotted at 10 min intervals. (d) Schematic diagram of the yeast cell cycle.
