 you will first need to create a single-column file that lists each non-UCSC setting and then
 use the &quot;-extra=&quot; option to specify this file when running hubCheck. For example,
 if you knew that a setting called &quot;ensemblAssemblyName&quot; was supported for use in track
 hubs by Ensembl, you could create a single line file that included  the setting
 &quot;ensemblAssemblyName&quot;. Then, when you want to check a hub that includes these extra
 trackDb settings, you would then specify this extra settings file on the command line:</p>
 <pre><code>$ hubCheck  -checkSettings -extra=http://genome.ucsc.edu/goldenPath/help/examples/hubExamples/hubCheckUnsupportedSettings/myExtraSettings.txt http://genome.ucsc.edu/goldenPath/help/examples/hubExamples/hubCheckUnsupportedSettings/hub.txt

 just examples and do not represent real trackDb variables for hubs at Ensembl.)</p>

 typically do work. As of 2020, they cost around 2-3 US cents/GB/month to store
 the hub data and 12-18 US cents per GB transferred, when the hub is used.
 For optimal performance, select a San Francisco / San Jose data center for the main
 UCSC site genome.ucsc.edu,  a Frankfurt/Germany data center for
 genome-euro.ucsc.edu and a Tokyo data center for genome-asia.ucsc.edu. You may
