Screenshots of data query in iHMS. This figure describes the search for multiple histone modification marks of a specific cell type. a In the Entry Screen, we choose Single Query. b A search for all profiled histone modification marks of H1 cell line. c The matched results are displayed on the bottom of the query page. Each line in the graph represents the histone modification states along the genomic region. By clicking the line on the left panel, we can view or hide the corresponding histone modification mark. d In the Batch Query page, multiple genomic locations can be searched at the same time
