Hi Damien, Custom tracks saved in session files have the typical 48 hour lifespan. However, custom tracks saved in sessions using a genomewiki login last for up to 4 months after the last time the session is accessed. (Note that we don't guarantee the 4-month custom track life spans; system failures might cause data loss before that date, so be sure to save custom tracks and be prepared to reload them and re-save the session.)
There is another option entirely, however. If you convert your BED data into the bigBed file format (described here: http://hgwdev.cse.ucsc.edu/goldenPath/help/bigBed.html) and put it in a web-accessible location for the Genome Browser to display, nothing will expire. Furthermore, only the portions of the file viewed by users on your end will be uploaded to UCSC at all (and once a portion is uploaded, it is saved here for subsequent access), so you will not need to deal with constant loading and reloading of data. The bigBed file format is relatively new, and we recommend using it over saving a session in genomewiki. The link above should contain all of the instructions for setting up a bigBed custom track, but please feel free to contact the list again if you have further questions. -- Brooke Rhead UCSC Genome Bioinformatics Group On 04/30/10 03:11, Damien Bruno wrote: > Dear UCSC Team, > > As part of our routine diagnostic work our laboratory relies heavily > on the UCSC Genome Browser for interpretation of whole-genome > microarray data.
