 settings with the Validate Hub tool. This tool can be accessed from the Track Hub page under 
 <a href="../../cgi-bin/hgHubConnect?#validateHub">the
 Validate Hub tab</a>. After entering your URL in the search box, 
 the tool runs hubCheck like so:</p>
 <pre>hubCheck -noTracks http://url.to.hub.txt</pre>
 <p>
 The noTracks setting speeds up the validation process but does not check for 
 the presence of your remotely hosted data track files. This tool checks your hub.txt, 
 genome.txt, and trackDb.txt settings and displays errors in bright red font, such 
 as "<font color="red">Missing required setting...</font>" and "<font color="red">Cannot open...</font>". The following picture shows

 <h3>Check hub settings using hubCheck utility</h3>
 <p>
 It is a good practice to run the command-line utility <em>hubCheck</em> on your track hub when you
 first bring it online and whenever you make significant changes. This utility by default checks
 that the files in the hub are correctly formatted, but it can also be configured to check a few
 other things including that various trackDb settings are correctly spelled and that they are
 supported by the UCSC Genome Browser. You can read more about using hubCheck to check the
 compatibility of your hub with other genome browsers <a href="#Compatibility"</a>below</a>.

 Here is the usage statement for the hubCheck utility:
