Figure 2. Spearman rank correlation for each gene.

The correlations are all with respect to the gold standard. The upper blue curve (stars) is our result; the green curve slightly below (rings) belongs to Ruan [11], while the lower red curve (plus-signs) is the mean of all other participants. The connecting lines are only guides for the eye. Most of the times, these results co-vary, but occasionally they have even different signs. The two breaks of the mean curve (gene numbers 13 and 38) come from some non-valid numbers in the presented results.
