Hi Frederico, From your email, I wasn't sure if you are trying to create super tracks (as suggested by your subject and first paragraph) or composite tracks (as suggested by your sample trackDb entry). Please see the following link for descriptions and also instructions on how to create trackDb entries for each: http://hgwdev.cse.ucsc.edu/~kent/src/unzipped/hg/makeDb/trackDb/README. (the 'SuperTracks', 'Composite Tracks' and '18. type bigWig' sections should be useful for you). Information about adding bigWigs to the browser can be found here: http://hgwdev.cse.ucsc.edu/~kent/src/unzipped/product/README.trackDb.
Also, here are examples of a composite track: http://genome.ucsc.edu/cgi-bin/hgTrackUi?hgsid=193917389&c=chr21&g=wgEncodeMapability, and super track (this one contains several composite tracks, but please note that super-tracks can also contain non-composite tracks): http://genome.ucsc.edu/cgi-bin/hgTrackUi?hgsid=193917389&c=chr21&g=wgEncodeDNAseSuper If you are trying to create a composite track, I noticed that in the subtrack blocks your sample trackDb entry, you are missing values for the shortLabels and longLabels of your subtracks. Also, be sure that you are following the database loading procedure for bigWigs described in the '18. type bigWig' section of the first link above. You should end up with tables entitled NAME2 and NAME3, each with a single row pointing to the location of that subtracks' bigWig file in your file system. You shouldn't have a NAME table. If you have any further questions after reading the documentation, please contact us again at [email protected]. --- Luvina Guruvadoo UCSC Genome Bioinformatics Group Federico De Masi wrote: > Dear Colleagues, > > I have been setting up a local UCSC browser for our own purposes and > have been trying to consolidate similar tracks together, such as for the > Encode supertracks. > > No matter what I have tried, copying from the available information, I > do not manage to get the system to work. > > Here's an example of my trackDb.ra entry > > track NAME > compositeTrack on > type bigWig 0.00 700 > shortLabel BLAH > longLabel LONG BLAH > priority 0 > group GRP > > track NAME2 > subTrack NAME > shortLabel > longLabel > priority 1 > > track NAME3 > subTrack NAME > shortLabel > longLabel > priority 2 > > When I insert this into trackDB (together with other tracks), I get the > tracks NAME, NAME2 and NAME3 created.
