 the Gateway page to open up the Genome Browser with the annotation track displayed.</p>
 <p>
 The Genome Browser also provides a <a href="../customTracks/custTracks.html" 
 target="_blank">collection of custom annotation tracks</a> contributed by the UCSC Genome 
 Bioinformatics group and the research community.</p> 
 <p>
 <strong>NOTE:</strong> If an annotation track does not display correctly when you attempt to upload 
 it, you may need to reset the Genome Browser to its default settings, then reload the track. For 
 information on troubleshooting display problems with custom annotation tracks, refer to the 
 troubleshooting section in the <a href="#CustomTracks">Creating custom annotation tracks</a>

+open source <a href="http://www.mariadb.org" target="_blank">MariaDB</a> relational database driving the
 Genome Browser, displays genomic data as columns of text rather than as graphical tracks. For more 
 information on using the Table Browser, see the section <a href="#TableBrowser">Getting started: on 
 the Table Browser</a>.</p>
 
 <h6>Opening the Genome Browser from external gateways</h6>
 <p>
 Several external gateways provide direct links into the Genome Browser. Examples include: 
 <a href="https://www.ncbi.nlm.nih.gov/entrez/" target="_blank">Entrez Gene</a>, 
 <a href="https://www.ncbi.nlm.nih.gov/IEB/Research/Acembly/index.html" target="_blank">AceView</a>, 
 <a href="http://www.ensembl.org/" target="_blank">Ensembl</a>, 
 <a href="http://supfam.mrc-lmb.cam.ac.uk/SUPERFAMILY/" target="_blank">SuperFamily</a>, and 
 <a href="http://www.genecards.org/" target="_blank">GeneCards</a>. Journal articles can also link 
 to the browser and provide custom tracks. Be sure to use the assembly date appropriate to the 
 provided coordinates when using data from a journal source.</p>

 <em>Chromosomes</em> contains the assembled sequence for the genome in separate files for each 
 chromosome in a zipped fasta format. The main assembly can be found in the <em>chrN.fa</em> files, 
 where <em>N</em> is the name of the chromosome.  The <em>chrN_random.fa</em> files contain clones 
 that are not yet finished or cannot be placed with certainty at a specific place on the chromosome. 
 In some cases, the <em>chrN_random.fa</em> files also contain haplotypes that differ from the main
