bigMaf example
--------------
You can read more about preparing the files necessary for a bigMaf track
on `UCSC's bigMaf help page
<https://genome.ucsc.edu/goldenPath/help/bigMaf.html>`_. The following code
uses the example files provided by UCSC.

This code is automatically run and the built trackhub is uploaded to the
`trackhub-demo <https://github.com/daler/trackhub-demo>`_ repository. You can
view the live hub using `this link <http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg38&hubUrl=https://raw.githubusercontent.com/daler/trackhub-demo/master/example_bigMaf_hub/bigMaf.hub.txt&position=chr22_KI270731v1_random>`_.
