Figure 4
The positions of transcript distribution peaks for all split-cell simulations, colour-coded according to the fit with the real data, predict an average number of transcripts per gene. This figure summarizes the data from all the split-cell simulations by representing each model transcript abundance distribution as a single point at the position of its peak. The points are color coded according to the rms (root mean square) distance from the real data (blue, best fit; brown-black, worst fit), and clearly show the clustering of the best-fit distributions in one region of the graph. X-axis: transcript copy number for a gene; y-axis: the number of genes with a given transcript copy number.
