Dear Nathan,

Thank you for your patience. Unfortunately, the links that you sent are no 
longer working because the custom track can't find the files. I have posted 
comments below your quoted questions.

"I have crafted a URL from the templates given on the docs page, and the name 
appears in the 'Custom Tracks' seciton, but not in the image. I just get the 
description above the track, and nothing on the left hand side."

Did you follow the instructions on the following page?

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

Just to be sure do you have the following description field in your track line?

description="Image title of your choice"


"Also I have previously seen direct links to gzipped wig files e.g."

Yes, it is possible to input a URL to a gzipped file.


"It happens that this file contains the appropriate header lines, but I'd like 
try this with a BED file (from and archive) which has no header. Is there a way 
I can pass the required attributes via the URL?"

If the files can be obtained via url, you can give a link to a url that 
contains the header lines followed by the url of the BED file you are 
interested in.

Hope this helps. If you have further questions, please don't hesitate to 
contact the mailing list.

Hi Mary

Thanks for the link.  This is very helpful, but I am struggling with one aspect 
of attaching a bigBed file, namely that I can't get the track name to display 
in the image.

I have crafted a URL from the templates given on the docs page, and the name 
appears in the 'Custom Tracks' seciton, but not in the image. I just get the 
description above the track, and nothing on the left hand side.

This is the test URL I am using:

http://genome.ucsc.edu/cgi-bin/hgTracks?org=mouse&position=chr6:52139181-52142206&hgct_customText=track%20type=bigBed%20name=%22XT67E1_undiff_H3K4me3%2dChIP%2DSeq%22%20description=%22XT67E1_undiff_H3K4me3%22%20visibility=full%20bigDataUrl=http://www.ebi.ac.uk/~njohnson/GSM397402_XT67E1_undiff_H3K4me3%2dChIP%2DSeq.bigbed

Also I have previously seen direct links to gzipped wig files e.g.

http://genome.ucsc.edu/cgi-bin/hgTracks?db=mm9&hgt.customText=ftp://ftp.ncbi.nih.gov/pub/geo/DATA/supplementary/samples/GSM397nnn/GSM397402/GSM397402_XT67E1_undiff_H3K4me3%2DChIP%2DSeq.wig.gz

It happens that this file contains the appropriate header lines, but I'd like 
try this with a BED file (from and archive) which has no header. Is there a way 
I can pass the required attributes via the URL?

Thanks

Nath
