[Genome] Wiggle track

[Brooke Rhead]

Hello Peter,

This page is probably the most useful for figuring out how do display 
wiggle data as a custom track (apologies if you have already looked at it):

http://genome.ucsc.edu/goldenPath/help/wiggle.html

The first thing you need to do is add this line before any of the data:

track type=wiggle_0

This is the only required track definition line for a wiggle track.  If 
you want the data to be autoscaled by default, you can add 
"autoScale=on" to the track definition line, like so:

track type=wiggle_0 autoScale=on

(You can also just make this selection with the track controls after you 
have made the custom track . . . click on the mini-button on the far 
left-hand side of your track in the Genome Browser.)

Another thing you need to do is sort your lines of data so that the 
chromosome positions are in ascending order.  You will get an error if 
they are out of order.

Now you can simply paste the data into the box on the custom track page. 
  I was able to successfully load this:

track type=wiggle_0 name=myWiggleTrack autoScale=on
