Heat maps—macrophages data. Graphical heat map presentation of the temporal connectivity structure for the macrophage gene expression time series. (a), (b), and (c): Heat matrices for experiments CMV (a), IFNG (b), and CMV+IFN (c) inferred with the BGM model. (d), (e), and (f): Heat matrices for experiments CMV (d), IFNG (e), and CMV+IFN (f) inferred with the novel model. Each heat map indicates the estimated posterior probability of two time points being assigned to the same compartment (mixture component). The probabilities are represented by a grey shading, where white corresponds to a probability of , and black corresponds to a probability of . The numbers on the axes represent the time points of the time course experiment.
