Hello Andrew, There is no actual set size limit, but the browser will time out for larger files. This is a function of both file size and network communication speeds for data transfer. I suppose a small file could time out due to a slow network - maybe you want to test for this situation first. I do not think this is an access problem - a different error would occur (error reporting 'can't access ....", not just a time out with a blank screen), but you could also test for this case with a very small file.
Good news is that there are some better solutions for large datasets. These types of custom track load quicker and are zippier in the display. Try either bigWig or bigBED or BAM. Click on the file types from the Custom track submission page to understand the formats, conversion utilities, and how to construct the submission string. The most important difference is that the data would stay on your own server - the submission string will include a url. This can be http, ftp, or a file that is local to the computer you are working from (although, for the last option, be aware that others will not be able to view your track). If you use a user/password in your url, characters need to be escaped for them to pass correctly. Ask if you need clarification about this. If you file is truly small and you think something else is going on - we can double check for format issues. Create the smallest file size that presents the problem and either send as an attachment to just me (not the list) if really small or send an ftp/http link if larger and I'll download that way. Please include the target database, your CT submission string, and any settings you have made. Follow-up is welcomed, Jennifer --------------------------------- Jennifer Jackson UCSC Genome Informatics Group http://genome.ucsc.edu/ On 3/18/10 8:11 AM, Andrew Gagne wrote: > Hi, > > I was wondering if there is a file size limit for custom tracks in the > genome browser. > > I tried searching and was not able to find a current answer.
