[Genome] download browser graphics programmatically

[Hiram Clawson]

Good Morning Bob:

You can use wget to fetch the browser page and its associated .gif
graphic.  The resulting html file ends up with an unusual name,
but the .gif file is there too.  For example:

wget --no-directories --recursive --follow-tags=img --html-extension \
--convert-links \
'http://genome.ucsc.edu/cgi-bin/hgTracks?hgt.customText=http://genome-test.cse.ucsc.edu/~hiram/ctDb/bedWigGtfPsl.txt'

This causes the loading of the custom tracks specified, which also controls which tracks are
displayed and position, note the browser specifications in the custom track file:
	http://genome-test.cse.ucsc.edu/~hiram/ctDb/bedWigGtfPsl.txt

The resulting .gif file is named something like: hgt_genome_34c6_9eae80.gif
The hex ID numbers there will be different each time.
For this particular example, as a bonus, you also get the ideogram graphic:
	 hgtIdeo_genome_34c6_9eae80.gif
