+<h2>Description</h2>
+
+<p> This track collection shows <a href="https://sites.google.com/site/revelgenomics/"
+target="_blank">Rare Exome Variant Ensemble Learner</a> (REVEL) scores for predicting
+the deleteriousness of each nucleotide change in the genome.
+</p>
+
+<p>
+REVEL is an ensemble method for predicting the pathogenicity of missense variants 
+based on a combination of scores from 13 individual tools: MutPred, FATHMM v2.3, 
+VEST 3.0, PolyPhen-2, SIFT, PROVEAN, MutationAssessor, MutationTaster, LRT, GERP++, 
+SiPhy, phyloP, and phastCons.  REVEL was trained using recently discovered pathogenic 
+and rare neutral missense variants, excluding those previously used to train its 
+constituent tools.  The REVEL score for an individual missense variant can range 
+from 0 to 1, with higher scores reflecting greater likelihood that the variant is 
+disease-causing. 
+</p>
+
+<h2>Display Conventions and Configuration</h2>
+<p>
+There are four subtracks for this track: one for every nucleotide showing
+a score for the mutation represented by a mutation from the reference to that
+nucleotide. All subtracks show the REVEL ensemble score on mouseover, representing
+each of the possible &#126;9 billion SNVs in the genome. The score is an aggregation 
+of the outputs of the 13 tools.  
+</p>
+
+<p>
+<b>Single nucleotide variants (SNV):</b> For SNVs, at every
+genome position, there are three values per position, one for every possible
+nucleotide mutation. The fourth value, &quot;no mutation&quot;, representing 
+the reference allele, e.g. A to A, is always set to zero.
+<br>
+When using this track, zoom in until you can see every basepair at the
+top of the display. Otherwise, there are several nucleotides per pixel under 
+your mouse cursor and instead of an actual score, the tooltip text will show
+the average score of all nucleotides under the cursor. This is indicated by
+the prefix &quot;~&quot; in the mouseover. Averages of scores are not useful for any
+application of REVEL.
+</p>
+
+<h2>Data access</h2>
+<p>
+REVEL scores are available at the 
+<a href="https://sites.google.com/site/revelgenomics/ target="_blank">
+REVEL website</a>.  
+The site provides precomputed REVEL scores for all possible human missense variants 
+to facilitate the identification of pathogenic variants amoung the large number of 
+rare variants discovered in sequencing studies.
+
+</p>
+
+<p>
+The REVEL data on the UCSC Genome Browser can be explored interactively with the
+<a href="../cgi-bin/hgTables">Table Browser</a> or the
+<a href="../cgi-bin/hgIntegrator">Data Integrator</a>.
+For automated download and analysis, the genome annotation is stored at UCSC in bigWig
+files that can be downloaded from
+<a href="http://hgdownload.soe.ucsc.edu/gbdb/$db/revel/" target="_blank">our download server</a>.
+The files for this track are called <tt>a.bw, c.bw, g.bw, t.bw</tt>. Individual
+regions or the whole genome annotation can be obtained using our tool <tt>bigWigToWig</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 tools can also be used to obtain features confined to given range, e.g.
