Rank fraction vs. p-values (left axis) and peak amplitudes (right axis) of the peaks in Fig. 3d (see text). Here the p-values correspond to the PFA of the peaks. The dashed lines provide the detection threshold for the corresponding false discovery rate α_FDR. Any cross below a detection threshold corresponds to a detection. The detection thresholds are determined by the greatest p-value below the corresponding continuous line (for details, see Miller et al. 2001).
