D-statistic versus FDR relationship at putative TREs, across the time-series (IGB view). Examples of enrichment fragments are observed within and upstream of the second intron of the HIC gene (pink). The upstream fragment is possibly un-annotated (UA), in so far as no RefSeq annotation is available. The top four tracks represent the HisH4 p-value graphs at 0 (red), 2 (light-blue), 8 (dark-blue) and 32 (green) hours, scaled appropriately for comparison; the subsequent tracks represent the d-statistic (top) and FDR (bottom) pair for the 0–2 (red), 2–8 (cyan) and 8–32 (blue) hour time intervals. The horizontal lines associated with the FDR data refer to the 5 percent threshold in each case.
