Correlation in expression profiles. Correlation in expression patterns between the (a) human-mouse (Hs-Mm) and (b) human-worm (Hs-Ce) orthologous pairs from the benchmarked methods versus the average proteome size. Vertical error bars show the standard deviation from the average correlation coefficient. The trendline shown is a linear regression trendline. The methods having a fourth letter 'B' behind the method name, shown as squares in the graph, are group orthology methods in which only the best scoring pairs are taken into account.
