Supplementary Figure 3: A web interface that integrates data from of Roadmap and the UCSC genome browser.
From: GIGGLE: a search engine for large-scale integrated genome analysis

(a) Users specify either a single interval or file to upload as the query, and the server responds with the GIGGLE results from an index in a heatmap. In this case the index is of CHROMHMM prediction from Roadmap. The color of each cell indicates the GIGGLE score, and users can click on a cell (e.g., Myoblast enhancers, marked in red) for more information. (b) When a cell is selected by the user, a window opens that contains the list of intervals in that particular Roadmap cell type/genome state annotation that overlap the query. Each interval is a link that can be followed (e.g., chr1:33642000-33642800, marked in red) for more information. (c) When an interval is selected, that interval becomes a query to a GIGGLE index of the UCSC genome browser tracks. The result gives the set of tracks that contain an interval that overlaps the query, and the web interface opens a window with a “smartview” where only those tracks with overlaps are displayed.
