           <p>
           During the first decade of the ENCODE project (2003-2014), 
           UCSC coordinated all project data, 
           hosting genome browser tracks and download files for all Consortium experiments.
           UCSC also developed tools for locating and accessing ENCODE data as well as
           outreach and tutorial materials to help the user community.
           The <em>ENCODE Data at UCSC</em> resources below are those developed during
           this period.  For newer data and outreach materials, consult the <em>ENCODE Project</em>
           section.

             How do I display ENCODE data from GEO in the genome browser?
           <p>
             <b><font COLOR="#006666">Response:</font></b><br>
             Please avoid loading GEO data as a custom track! Rather, as nearly all ENCODE data at GEO
             are already hosted as tracks on the UCSC browser, load the existing corresponding track.
           </p>
           <p>
             Take note of the GEO sample accession (GSM) number and enter it into the Track Search tool
             accessible from the left side of the ENCODE portal page by clicking <a href="/ENCODE/search.html" target="_blank">Search</a>, for example
             <a href="../../cgi-bin/hgTracks?db=hg19&hgt_tSearch=1&tsCurTab=simpleTab&tsSimple=GSM999240" target="_blank">GSM999240</a>.
             Or use the Advanced Track Search page and select &quot;GEO sample accession&quot; from the pull down menu displaying
             &quot;Cell, tissue or DNA sample&quot.  Click the box next to your track resulting from the
             search and the &quot;View in Browser&quot; button.
           </p>
           <p>
             If you have data that is not already in the browser we recommend converting your BED files to
             <a href="../../goldenPath/help/bigBed.html" target="_blank">bigBed format</a>.
             You could download our source tools for converting from BED to bigBed (as described in the previous link)
             or use the tools at the <a href="http://galaxyproject.org/" target="_blank">Galaxy</a> website. For questions regarding
             Galaxy you will have to contact them directly.

             Where can I find the ENCODE growth protocol for a specific cell type? For example RCC 7860?
           <p>
             <b><font color="#006666">Response:</font></b><br>
             To find a specific protocol, for example for human RCC 7860 cells, from the ENCODE portal navigate 
             to the <a href="/ENCODE/cellTypes.html" target="_blank">Human Cell Types</a> page. Under the "Documents"
             column for RCC 7860, click the link to connect to see the growth protocol named after the lab that
             provided the document, in this case &quot;Crawford&quot;.
           <p>
             Another path to ENCODE protocols is from the link <a href="/ENCODE/protocols" target="_blank">/ENCODE/protocols/</a>.
             Navigate to the cell protocols and then human directories to find the link to the
             same RCC 7860 protocol file as linked on the above <a href="/ENCODE/cellTypes.html" target="_blank">Human Cell Types</a> page.
           <p>

             A quick way to view the list of transcription factors mapped by ENCODE is to view the ChIP-seq
             matrix for either <a href="/ENCODE/dataMatrix/encodeChipMatrixHuman.html" target="_blank">human</a> 
             or <a href="/ENCODE/dataMatrix/encodeChipMatrixMouse.html" target="_blank">mouse</a>.
             Targets are listed horizontally across the top, indicating available mapped transcription factor data.
             Clicking on the green highlighted boxes will bring you to experiment data specific to the
             corresponding cell type and target.
           <p>
             Another option is to use the <a href="../../cgi-bin/hgTracks?db=hg19&hgt_tSearch=1&tsCurTab=advancedTab"
                                             target="_blank">Track Search</a> or <a href="../../cgi-bin/hgFileSearch" target="_blank">File Search</a>

             By using the <a href="../../cgi-bin/hgTables" target="_blank">Table Browser tool</a>
             you can add your ChIP-seq information as a custom track and then use the &quot;intersection&quot; 
             feature to intersect the Txn Factor ChIP track table listed under the Regulation group with your
             custom track. Note, your custom track should contain ChIP-seq regions in BED format, for more information
             visit our <a href="../../goldenPath/help/customTrack.html" target="_blank">custom tracks</a> page.
           <p>

             For files named similar to xxxV2, often the &quot;V2&quot; refers to a second version that revokes earlier  versions
             that are therefore not displayed in the browser.  Revoked files are still available for download, but they  will
             be indicated as &quot;replaced &quot; or &quot;revoked&quot; in the related metadata file named &quot;files.txt&quot;

             This is not recommended.  While ENCODE filenames have some metadata embedded, the information there is not complete nor easily extracted.
             Rather, use the file's metadata, for example in &quot;files.txt&quot;, or access metadata in the following places:
             <ol>By opening &quot;files.txt&quot; - the metadata file located in each track's corresponding download directory.
               <br/>By clicking the blue down-arrow next to each subtrack listed on a track's Track Settings page.
               <br/>By using <a href="/ENCODE/search.html" target="_blank">Track Search or File Search</a> to filter files by metadata.
               <br/>By using the <a href="../../cgi-bin/hgTables" target="_blank">Table Browser tool</a>
               and setting &quot;Group&quot; to &quot;All Tables&quot; and selecting the &quot;metaDb&quot; table. Click
               the &quot;describe table schema&quot; button to learn more about the metaDb table.
               <br/>By using the <a href="../../goldenPath/help/mysql.html" target="_blank">public MariaDB database</a>
               to query the metaDb table for each database.
             </ol>  
             The metadata uses controlled vocabulary (cv.ra), which can be downloaded as a text file

             <b><font color="#006666">Response:</font></b><br>
             The score (between 0-1000) determines how darkly an item is
             displayed in the browser (with 1000 being black).
             The darkness of an item's box is proportional to the maximum signal strength observed in
             any cell line.
           <p>
             To find out exactly how score has been calculated for a specific track, contact the lab that created the data.
             There are often several links to authors' labs in the credits

             The ENCODE BED files you are looking to download are the 'peak calls', which are

             <a href="../../FAQ/FAQformat.html#ENCODE">here</a>. For example,
             within the database mentioned (H3K27ac histone mark in GM12878 cells) there is a BED

             The total volume of ENCODE data are greater than 31 TB. Unfortunately, it is not
             possible for you to obtain a disk copy, however, there is a new protocol to try
             called UDR (UDT Enabled Rsync). UDR provides users much faster download rates.</p>
           <p>
             Here is an example using UDR, once installed, to download all the mouse mm9 ENCODE
             information:</p>
           <pre class="code">$ udr rsync -avP hgdownload.soe.ucsc.edu::goldenPath/mm9/encodeDCC/ /my/local/mm9/</pre>
             Please read more about the new UDR method <a href="../../ENCODE/newsarch.html#091213"

           <p>
             For those not downloading high amounts of data, we highly recommend using rsync.
             For example:</p>
           <pre class="code">$ rsync -a -P rsync://hgdownload.soe.ucsc.edu/goldenPath/hg19/encodeDCC/wgEncodeDir/wgEncodeFile ./</pre>
           <p>
             Using rsync has the advantage of starting up where it left off after a failure, when run again.

             How are the columns signalValue and peak calculated in narrowPeak files? For example,
             I want more information about UW Histone &quot;wgEncodeUwHistone...PkRep1.narrowPeak&quot; files.
           <p>
             <b><font color="#006666">Response:</font></b><br>
             The <a href="../../FAQ/FAQformat.html">File Format FAQ</a> provides explanations
             about various file formats. Also a file's related Track Description page may include important information,
             such as  the <a href="../../cgi-bin/hgTrackUi?db=hg19&g=wgEncodeUwHistone">UW Histone</a>
             &quot;Methods section&quot;, which describes how data were processed to produce peaks. In the &quot;Credits&quot; section
             there is also a lab contact. To request further information for UW Histone data, for example,
             you could contact the lab to learn more about the peak calling algorithm or other methods involved.
           </p>
           <p>
             When using the <a href="../../cgi-bin/hgTables">Table Browser</a> there is a &quot;describe table
             schema&quot; button that gives information similar to that located in the File Format FAQ, plus the related Track Description.
           </p>
           <p>
             For example with settings &quot;group: Regulation&quot;, &quot;track: UW Histone&quot;, and
             &quot;table: wgEncode...PkRep#&quot;, if you click the &quot;describe table schema&quot; button you will
             find definitions for signalValue and peak. Scrolling down you will find the related Track Description
             for UW Histone with the explanation for peak calling under &quot;Methods&quot; and the laboratory contact under &quot;Credits&quot;.

             <b><font color="#006666">Response:</font></b><br>
             An excellent resource to review is the ENCODE Software Tools page, located on the lefthand side
             of the <a href="/ENCODE/">ENCODE portal</a> under &quot;Software Tools.&quot;
             Click through to the <a href="/ENCODE/encodeTools.html">Software Tools Used to Create the ENCODE Resource</a>
             and here you can find references for the various peak calling algorithms under &quot;ChIP-seq Peak Callers&quot;.
           <p>
             By visiting various ENCODE tracks such as <a href="../../cgi-bin/hgTrackUi?db=hg19&g=wgEncodeHaibTfbs">HAIB TFBS</a>,
             <a href="../../cgi-bin/hgTrackUi?db=hg19&g=wgEncodeSydhTfbs">SYDH TFBS</a>, or
             <a href="../../cgi-bin/hgTrackUi?db=hg19&g=wgEncodeUwHistone">UW Histone</a>
             you can learn more about the processes each lab used to generate peaks, and pick a method suitable for your data.
             Since these data were not generated by the UCSC Browser group, questions about the data methods need to be
             directed to the corresponding lab. Under the &quot;Credits&quot; section you will find a contact for further
             questions left unanswered by reading the descriptions.

             I am making a public hub for my paper, is there an example html file to use for my data description?

             <b><font color="#006666">Response:</font></b><br>
             The browser's <a href="../../cgi-bin/hgHubConnect?" target="_blank">public hubs</a>
             provide excellent examples of hub documentation. Here are two examples of track 
             description pages from the ENCODE Analysis hub:
             <p>
               <a href="http://ftp.ebi.ac.uk/pub/databases/ensembl/encode/integration_data_jan2011/hg19/uniformTfbs.html">

             <p>
               <b>Useful tips when writing your track descriptions:</b>
               <li>It is best to assume a broad audience of students as well as researchers.  Spelling out common acronynms,
                 for example, may be useful for those who are new to genomics.</li>
               <li>The paper's abstract may be a good start for your track's "Description" section.</li>
               <li>Provide as much detail as possible in the "Methods" section.</li>
               <li>A email address must be prominently displayed for questions relating to the track.</li>
             </p>

               Note: We recommend a minimal number of default visible tracks in your trackDb.txt to
