Dependence, for the detection of Bone qualifiers, of the sensitivityS on the χ² filtering step parameterN _χ² (number of qualifiers passed after χ² ranking). For a given N _χ² , the reduced C2C12 data set is classified by GENNC with fixedk = 2, and with the Correlation Filter thresholdP ₀ adjusted to maintain a false-positive rateFP_u  = 0.12. The maximum sensitivity occurs forN ${}_{\chi 2}^{*}$  = 2,000,S* = 0.44
