Intensity and breadth are distinct attributes of H3K4me3 peaks. H3K4me3 peaks are typically found upstream and downstream of the TSSs of active genes (TTS = transcription termination site). Peak intensity describes the level of H3K4me3 enrichment normalized to peak width. Peak breadth describes the width of H3K4me3 enrichment
