Correlations between evaluation methods. A selection of 12 correlations between evaluation methods using the average score of 2D fingerprint ECFP4 for the three collection of data sets: MUV (open triangles), DUD (open circles), and ChEMBL (filled circles). The maximum value is 100.0 for EF(1%), and 20.0 for EF(5%). For RIE, the maximum value of the ChEMBL data sets was used, i.e. 18.1 for RIE(20), and 63.2 for RIE(100). Linear regression curve is shown for all 88 targets (thin line) and for the 67 targets of MUV and ChEMBL (thick line).
