Hi Jose, What you have described is a "bedgraph" file. Perhaps changing the file extension to "bedgraph" will be enough, if not you might be required to enter a track line. See UCSC for details.

I changed it to bedgraph and can no longer view in UCSC (the button to view in UCSC was not there anymore). I had it in bed format subsequently and put in a header. I was looking at the bedgraph/wiggle header documentation on UCSC but don't find any that describes displaying scores in histogram format. I saw that we can change colour the intensity of the bars based on scores though. Jose On Thu, May 10, 2012 at 10:27 PM, James Robinson <

Good Evening Jose: Please note the types of graphing formats you can display at UCSC: http://genomewiki.ucsc.edu/index.php/Selecting_a_graphing_track_dat a_format I would recommend converting your bedgraph file to a bigWig file and display that via a remote URL. This would be your most efficient mechanism of display. --Hiram To: "James Robinson" <jrobinso@broadinstitute.org> Cc: galaxy-user@lists.bx.psu.edu Subject: Re: [galaxy-user] Displaying bed files in ucsc I changed it to bedgraph and can no longer view in UCSC (the button to view in UCSC was not there anymore).

Hello, I have a bed file in this format: chr# start end scores. I tried to view it in ucsc main but it showed only where the fragments are(based on the start and end coordinates) with numerical scores beside each fragment. How do I view the file as a histogram format? What format will I need to convert the file to and where can I do the conversion? Any advise is greatly appreciated! Jose

In the title information you need to include UseScore information including the range you want to cover with your histogram. There is a section in the UCSC website that explains the content: http://genome.ucsc.edu/FAQ/FAQformat.html#format1 For stating the range of your histogram: scoreMin=X scoreMax=X. This will mean that the greyscale shading uses the two X values as the value for white and black, all other points will be an even range like the example on the UCSC browser page. When I was doing this the information I used was wiggle format: track type = wiggle_0 name="name of track" description="description" useScore=1 scoreMin=0 scoreMax=6. ChrNo StartPos FinishPos Score Hope that makes sense/helps lizzy Hello, I have a bed file in this format: chr# start end scores.

Please note the arguments you can use in a track line for a type=wiggle_0 format file: http://genome.ucsc.edu/goldenPath/help/wiggle.html The arguments useScore, scoreMin, scoreMax have no meaning with a wiggle track. A wiggle track does not display items in a gray-scale fashion, it draws a graph of the data values. --Hiram To: wongxr@gmail.com Cc: galaxy-user@lists.bx.psu.edu Subject: Re: [galaxy-user] Displaying bed files in ucsc In the title information you need to include UseScore information including the range you want to cover with your histogram.

Thank you for the advise. I am able to view now when I use track type=wiggle_0 but I can only do it a few chr at a time which is good enough. Just curious, what track type do I type in when I want it to be bedgraph? It seems the _0 was important for wiggle. Jose

With your setting of type=wiggle_0 and using bedGraph format, you happen to have selected the most inefficient mechanism of displaying this data as explained here: http://genomewiki.ucsc.edu/index.php/Selecting_a_graphing_track_da ta_format That's the reason why you can only see a few chromosomes of data. The immense amount of data in your file cannot survive the transfer time-out. You could get a little better performance with type=bedGraph: http://genome.ucsc.edu/goldenPath/help/bedgraph.html See also: http://genome.ucsc.edu/goldenPath/help/customTrack.html However, in order to see all of your data you must use the bigWig format. I'm sure there is a bedGraph to bigWig conversion function at galaxy. Use that function and then submit a single track line to describe the data options and specify the bigDataUrl to your bigWig format file. This will save you much time and trouble. http://genome.ucsc.edu/goldenPath/help/bigWig.html --Hiram To: "Hiram Clawson" <hiram@soe.ucsc.edu> Cc: "Liz Ashley" <lizzilou@hotmail.com>, galaxy-user@lists.bx.psu.edu Subject: Re: [galaxy-user] Displaying bed files in ucsc Thank you for the advise.
