If you would like to share a URL that your colleague can click on directly, rather than loading it
in the Custom Track tool (as in Example #5), then the URL will need a few extra parameters. Let's
assume that your data is on a server at your institution in one of the large data formats:
bigBed,
bigWig,
bigPsl,
bigBarChart,
bigChain,
bigInteract,
bigGenePred,
bigMaf,
bigNarrowPeak,
+bigMethyl,
BAM,
CRAM, or
VCF.
In this case, the URL must include an hgct_customText parameter, which
simulates the text box on the Custom Tracks page. Also, the URL must include
the bigDataUrl that points to the data file on your server.
So, a clickable URL that opens a remote bigBed track for the hg18 assembly to a certain location on
chr21 would look like this:
http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg18&position=chr21:33038447-33041505&hgct_customText
=track%20type=bigBed%20name=myBigBedTrack%20description=%22a%20bigBed%20track%22%20visibility=
full%20bigDataUrl=http://genome.ucsc.edu/goldenPath/help/examples/bigBedExample.bb
Tip: Multiple tracks can be placed into one custom track submission. To do so,
