DANIO-CODE as native danRer11 tracks, alpha only.

Converts the DANIO-CODE consortium's public track hub for danRer11 into a
native trackDb: 897 stanzas under one superTrack, with 11 containers for
RNA-seq, CAGE-seq, ChIP-seq, 3P-seq, Hi-C, regulatory elements, cell types,
COPEs/DOPEs, validated enhancers, conservation and consensus promoters.

The 879 data files, 69 GB, are mirrored under /gbdb/danRer11/danioCode and are
byte-identical to the consortium's copies. Four cell-type subtracks are left
out because their files 404 on the consortium's server.

+<h2>Description</h2>
+
+<p>
+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.
+</p>
+
+<p>
+This track is part of the <a href="hgTrackUi?g=danioCode">DANIO-CODE</a> collection.
+</p>
+
+<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.
+</p>
+
+<h2>Methods</h2>
+
+<p>
+The DANIO-CODE consortium assembled 1,802 zebrafish developmental genomics datasets,
+1,438 of them already published and 366 generated by consortium members, and
+reprocessed all of them from the raw sequencing reads so that samples from different
+laboratories and different protocols can be compared with each other. ChIP-seq and
+ATAC-seq were run through the ENCODE pipelines, CAGE-seq through the FANTOM pipeline,
+and Hi-C and 4C-seq through the pipelines of the groups that produced them. The
+pipelines are published at
+<a href="https://gitlab.com/danio-code" target="_blank">gitlab.com/danio-code</a>, and
+samples were assigned to developmental stages using ZFIN and ENCODE nomenclature. See
+Baranasic <em>et al</em>. 2022 for details.
+</p>
+
+<p>
+ChIP-seq libraries were mapped and peak-called with the ENCODE ChIP-seq pipeline. The
+samples come from 10 laboratories, among them the Schier, Cairns, Bartel, Zon,
+Horsfield, Driever, Skarmeta, Shkumatava, Mathavan and Mueller laboratories, and were
+originally deposited under accessions including GSE32483, GSE41458, GSE44269,
+GSE48254, GSE75356, GSE84602 and GSE95033. The accession of each sample is shown in
+its track description line.
+</p>
+
+<p>
+At UCSC the tracks were converted from the consortium's public track hub at
+<a href="https://trackhub2.genereg.net/DANIO-CODE/DANIO-CODE.hub.txt" target="_blank">
+trackhub2.genereg.net/DANIO-CODE</a> with the script
+<a href="https://github.com/ucscGenomeBrowser/kent/tree/master/src/hg/makeDb/scripts/danioCode"
+target="_blank">danioCodeHubToRa.py</a>, and the data files were copied from the same
+server. The data themselves were not modified. The steps are documented in
+<a href="https://github.com/ucscGenomeBrowser/kent/blob/master/src/hg/makeDb/doc/danRer11/danioCode.txt"
+target="_blank">our makeDoc</a>.
+</p>
+
+<h2>Data Access</h2>
+
+<p>
+The data can be explored interactively in table format with the
+<a href="../cgi-bin/hgTables">Table Browser</a> or the
+<a href="../cgi-bin/hgIntegrator">Data Integrator</a> and exported from there to
+spreadsheet or tab-separated tables. From scripts, the data can be accessed through
+our <a href="https://api.genome.ucsc.edu">API</a>, track=<i>dcChIPseqComposite</i>.
+</p>
+
+<p>
+For automated download and analysis, the annotations are stored in bigWig and bigBed files that
+can be downloaded from
+<a href="http://hgdownload.soe.ucsc.edu/gbdb/danRer11/danioCode/" target="_blank">our
+download server</a>. Files are named after the target and the DANIO-CODE sample accession, for example <tt>CTCF_DCD002910SQ_signal.bigWig</tt> and <tt>CTCF_DCD002910SQ_peak.bigBed</tt>. Individual regions or the whole genome annotation can be
+obtained using our tool <tt>bigBedToBed</tt>, which can be compiled from the source code
+or downloaded as a precompiled binary for your system. Instructions for downloading
+source code and binaries can be found
+<a href="http://hgdownload.soe.ucsc.edu/downloads.html#utilities_downloads">here</a>.
+The tool can also be used to obtain features within a given range, for example
+</p>
+<pre>bigBedToBed http://hgdownload.soe.ucsc.edu/gbdb/danRer11/danioCode/CTCF_DCD002910SQ_peak.bigBed \
