[Genome] Custom track question

[Kate Rosenbloom]

Hello John Paul,

You can remove existing custom tracks from
the display when loading others via URL
by clearing the custom track file variable
for the assembly you are using.  To do this,
add the following to the URL
that loads the new custom tracks:

    &ctfile_db=

where 'db' is replaced with the genome assembly.

For example, for data displayed on the March 2006 (hg18)
browser, your URL would look similar to:

http://genome.ucsc.edu/cgi-bin/hgTracks? 
db=hg18&hgt.customText=your_URL&ctfile_hg18=

If this construct doesn't work for you, please contact
me directly.

Cheers,
     Kate
