 <h2>Description</h2>
 
 <p>
+This track is part of the <a href="hgTrackUi?g=danioCode">DANIO-CODE</a> track collection.
 ChIP-seq finds the places in the genome where a particular protein sits. Chromatin is
 crosslinked, sheared and pulled down with an antibody against the protein of interest,
 and the DNA that comes with it is sequenced. For histone modifications the result is a
 map of the chemical marks on the histones that DNA is wrapped around, and different
 marks tend to sit at different kinds of element: H3K4me3 at active promoters, H3K4me1
 and H3K27ac at enhancers, H3K27me3 at genes that are silenced by Polycomb, and
 H3K36me3 across the bodies of transcribed genes. For a transcription factor the result
 is a map of its binding sites.
 </p>
 
 <p>
 This track shows ChIP-seq data for 104 zebrafish samples across 17 developmental
 stages and 18 targets: the histone marks H3K4me3, H3K4me1, H3K27ac, H3K27me3,
 H3K36me3, H3K14ac and the histone variant H2AFV; RNA polymerase II with two antibodies
 (4H8 and 8WG16); and the transcription factors Pou5f3, Nanog, Sox10, Zic3, CTCF, Cdx4,
 Sall4, Mxtx2 and Gata1. These are the data the consortium used to segment the genome
 into chromatin states, which are shown in the
 <a href="hgTrackUi?g=dcComp">DC Elements</a> track.

 <h2>Display Conventions and Configuration</h2>
 
 <p>
 The track has two views that can be configured separately. <b>Signal</b> shows one
 auto-scaled coverage graph per sample. <b>Peaks</b> shows the enriched regions called
 from that signal, as blocks.
 </p>
 
 <p>
 Nothing is displayed until samples are selected on the configuration page, where they
 can be filtered by ChIP-seq target, developmental stage and sample. There are more than
 200 individual tracks, so select only the targets and stages you need.
