By default, the transcription and histone mark displays use a transparent overlay method of displaying data from a number of cell lines in a single track. Each of the cell lines in this track is associated with a particular color, and these colors are relatively light and saturated so as to work best with the transparent overlay. The color of the transcription and histone mark tracks match their versions from their lifted source on the hg19 assembly.
The DNase tracks, which were not lifted from hg19, are colored differently to reflect similarity of cell types. There are three DNase tracks starting with a transparent overlay DNase Signal Track to allow viewing signals from all 95 cell types in one track. The individual signals and the same coloring scheme can also be found in the DNase HS Track where processed peaks and hotspots are also called out as gray boxes with the darkness of each box reflecting the underlying signal value. Lastly, in the DNase Clusters track all observed hypersensitive regions in the different cell lines at the same location were clustered into a single box where a number to the left of the box indicates how many cell types showed a hypersensitivity -region and the darkness of the grey box is proportional to the the maximum value seen from one of +region and the darkness of the grey box is proportional to the maximum value seen from one of the underlying cell lines. Clicking on these item takes you to a details page where additional information displays, such as the list of cell types that combined to form the cluster in the DNase Clusters track.
The raw data for ENCODE 3 Regulation tracks can be accessed from Table Browser or combined with other data-sets through Data Integrator. For automated analysis and downloads, the track data files can be downloaded from our downloads server or queried using the JSON API or the Public SQL Individual regions or the whole genome annotation can be accessed as text using our utility bigBedToBed.
