 <h2>Description</h2>
 
 <p>
+This track is part of the <a href="hgTrackUi?g=danioCode">DANIO-CODE</a> track collection.
 Most messenger RNAs end in a poly(A) tail, and the position where that tail is added
 determines the length of the 3' untranslated region. That region carries the binding
 sites for microRNAs and RNA-binding proteins, so a transcript that uses a different
 poly(A) site can be regulated quite differently. 3P-seq (poly(A)-position profiling by
 sequencing) sequences the junction between the transcript and its poly(A) tail, which
 places the 3' end of the transcript directly.
 </p>
 
 <p>
 This track shows 3P-seq data for 15 zebrafish samples covering 7 developmental stages,
 from the 1-cell stage to the adult. Both the raw signal and the tag clusters called
 from it are shown. During the first hours of development, when the embryo still lives
 on maternally deposited RNA, poly(A) tails are actively lengthened and shortened, so
 these data change substantially from stage to stage.

 <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>Regions</b> shows the tag clusters as blocks.
 Nothing is displayed until samples are selected on the configuration page, where they
 can be filtered by developmental stage and by sample.
 </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>
 The 3P-seq samples come from the Bartel laboratory and were originally deposited under
 GSE32880 and GSE37453.
 </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>dc3PseqComposite</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 DANIO-CODE data accession, for example <tt>DCD007934DT_tagCluster.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/DCD007934DT_tagCluster.bigBed \
     -chrom=chr1 -start=20000000 -end=20100000 stdout</pre>
 
 <p>
 The original data files, and the sample and protocol metadata behind them, are
 available from the DANIO-CODE data coordination center at
 <a href="https://danio-code.zfin.org" target="_blank">danio-code.zfin.org</a> and from
 the consortium's track hub at
 <a href="https://trackhub2.genereg.net/DANIO-CODE/DANIO-CODE.hub.txt" target="_blank">
