 <h2>Description</h2>
 
 <p>
 DANIO-CODE is an international consortium that annotates the non-coding part of the
 zebrafish genome, in the same spirit as ENCODE for the human genome. Rather than
 cataloguing genes, it maps the sequences that control when and where genes are used:
 promoters, enhancers, chromatin states and the contacts between them. What sets the
 zebrafish effort apart is that it is centered on development, so the annotation is
 built stage by stage, from the fertilized egg through gastrulation and organogenesis to
 the adult fish.
 </p>
 
 <p>
 The consortium collected and reprocessed 1,802 zebrafish functional genomics datasets
 from a single pipeline per data type, so that samples from different laboratories can
 be compared with each other, and used them to annotate more than 140,000 candidate
 cis-regulatory elements across development. This collection shows those data on
 danRer11: RNA-seq coverage, CAGE-seq transcription start sites, ChIP-seq signal and
 peaks, 3P-seq polyadenylation sites, Hi-C chromosome folding, and the regulatory
 element annotations derived from them.
 </p>
 
 <p>
 The collection contains the following tracks. Each has its own description page with
 the details of that data type:
 </p>
 
 <ul>
   <li><a href="hgTrackUi?g=dcRNAseqComposite">DC RNA-seq</a> &mdash;
       strand-specific and unstranded read coverage for 361 RNA-seq samples across 31
       developmental stages.</li>
   <li><a href="hgTrackUi?g=dcCAGEseqComposite">DC CAGE-seq</a> &mdash; CAGE
       signal and tag clusters, which mark the positions where transcription starts.</li>
   <li><a href="hgTrackUi?g=dcChIPseqComposite">DC ChIP-seq</a> &mdash; signal
       and called peaks for seven histone modifications, RNA polymerase II and nine
       transcription factors.</li>
   <li><a href="hgTrackUi?g=dc3PseqComposite">DC 3P-seq</a> &mdash; signal and
       tag clusters marking the 3' ends of transcripts.</li>
   <li><a href="hgTrackUi?g=dcHiC_Composite">DC Hi-C</a> &mdash; insulation index
       and directionality index computed from Hi-C contact maps, used to locate the
       boundaries of topologically associating domains.</li>
   <li><a href="hgTrackUi?g=dcComp">DC Elements</a> &mdash; per-stage regulatory
       element annotation at five stages: ChromHMM chromatin states, PADREs, the
       consensus subset cPADREs, and DOPEs.</li>
   <li><a href="hgTrackUi?g=dcComp_cell_type">DC Cell Types</a> &mdash;
       regulatory elements assigned to a cell type using single-cell ATAC-seq.</li>
   <li><a href="hgTrackUi?g=dcCopes_and_dopes">DC COPEs DOPEs</a> &mdash; open
       chromatin regions that carry no histone mark at any stage, split by whether they
       stay open throughout development or only at some stages.</li>
   <li><a href="hgTrackUi?g=dcEvalidation">DC Enhancers</a> &mdash; a curated set
       of zebrafish enhancers tested in transgenic reporter assays.</li>
   <li><a href="hgTrackUi?g=dcComparativeGenomics">DC Conservation</a> &mdash;
       phastCons conservation across four cyprinid fishes, the conserved non-coding
       elements from it, and predicted CRISPR/Cas9 target sites, from the Shawn Burgess
       laboratory at NHGRI.</li>
   <li><a href="hgTrackUi?g=dcConsensus_promoters">DC Promoters</a> &mdash;
       consensus promoters called from the CAGE data.</li>
 </ul>
 
 <h2>Display Conventions and Configuration</h2>
 
 <p>
 Each of the tracks above is a container that groups many individual data files. Click a
 track name to open its configuration page, where samples can be selected by
 developmental stage, by sequencing sample, by ChIP-seq target and, for RNA-seq, by
 strand. Nothing is turned on by default; pick the samples you need, since turning on
 all of them at once will make the display very slow.
 </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 protocols can be compared. 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>.
 Samples were assigned to developmental stages using ZFIN and ENCODE nomenclature.
 Regulatory elements were predicted by segmenting the genome with ChromHMM using the
 histone modification data, then keeping the segments supported by an ATAC-seq peak; the
 resulting PADREs were classified further with a UMAP embedding of their accessibility
 and histone signal. Details are in Baranasic <em>et al</em>. 2022, and the data
 coordination center is at
 <a href="https://danio-code.zfin.org" target="_blank">danio-code.zfin.org</a>. The
 methods that apply to one data type are described on that track's own description page.
 </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> into native tracks 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>.

 <h2>Data Access</h2>
 
 <p>
 This is a collection of tracks; open the description page of an individual track above
 for the file names it uses and for examples.
 </p>
 
 <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>.
 </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>. Individual regions or the whole genome annotation can be obtained
 using our tools <tt>bigWigToBedGraph</tt> and <tt>bigBedToBed</tt>, which can be
 compiled from the source code or downloaded as precompiled binaries 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 tools can also be used to obtain features within a given range, for example
 </p>
 <pre>bigBedToBed http://hgdownload.soe.ucsc.edu/gbdb/danRer11/danioCode/consens.canonical.danRer11.bigBed \
     -chrom=chr1 -start=20000000 -end=20100000 stdout</pre>

 consortium's own analyses, can be downloaded from the DANIO-CODE data coordination
 center at <a href="https://danio-code.zfin.org" target="_blank">danio-code.zfin.org</a>.
