Description

This track provides an integrated display of DNase hypersensitivity in multiple cell types using overlapping colored graphs of signal density with graph colors assigned to cell types based on similarity of signal. The track is based on results of experiments performed by the John Stamatoyannapoulos lab at the University of Washington from September 2007 to January 2011 as part of the ENCODE project first production phase.

The signal graphs displayed here are also included in the comprehensive DNaseI HS track, which also provides peak and region calls and uses the same coloring based on similiarity of cell types (please note there is different coloring on the ENCODE hg38 Transcription track, Layered H3K4Me1 track, Layered H3K4Me3 track, and Layered H3K27Ac track, which match the coloring used in their previous versions lifted from the hg19 assembly).

Methods

Raw sequence data files were processed by the UCSC ENCODE DNase analysis pipeline described in the DNaseI HS track description. Signal graphs were normalized so the average value genome-wide is 1. Colors for the signal graphs were assigned by the UCSC BigWigCluster tool.

The cell types were clustered into a binary tree, a rainbow was cast to the leaf nodes providing coloring based on similarity.
