 <h2>Description</h2>
 
 <p>
+This track is part of the <a href="hgTrackUi?g=danioCode">DANIO-CODE</a> track collection.
 CAGE (cap analysis of gene expression) sequences only the very first bases of capped
 RNA molecules. Each read therefore marks one transcription start site, at base
 resolution. Because promoters usually fire from a small cluster of neighboring start
 sites rather than a single base, the individual start sites are grouped into tag
 clusters, and a tag cluster is a good working definition of an active promoter.
 </p>
 
 <p>
 This track shows CAGE data for 16 zebrafish samples spanning 12 developmental stages,
 from the 1-cell stage to the adult. Two kinds of data are shown: the raw signal, which
 is the number of transcription start sites seen at each base, and the tag clusters
 called from that signal. Zebrafish is a useful system for this because the promoters
 used by the mother's stored RNA and those used after the embryo's own genome switches
 on can sit within the same promoter region and are separable at this resolution.

 <h2>Display Conventions and Configuration</h2>
 
 <p>
 The track has two views that can be configured separately. <b>Signal</b> shows one
 coverage graph per sample, auto-scaled to the window. <b>Regions</b> shows the tag
 clusters as blocks; the score of a cluster reflects its expression, and the colors are
 taken from the consortium's files.
 </p>
 
 <p>
 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>
 CAGE libraries were processed with the FANTOM CAGE pipeline. Tag clusters were called
 from the mapped start sites. The samples in this track come from the Mueller
 laboratory and were originally deposited under SRA055273.
 </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>dcCAGEseqComposite</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>. Signal files are named after the DANIO-CODE sample accession, for example <tt>DCD001527SQ_signal.bigWig</tt>, and tag cluster files end in <tt>_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/DCD001527SQ_DCD011313DT_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
