Hi Alberto, You can specify other aspects of tracks with custom track "track lines": http://genome.ucsc.edu/goldenPath/help/hgTracksHelp.html#TRACK
Note that there are many settings applicable to wiggle tracks: http://genome.ucsc.edu/goldenPath/help/wiggle.html . . . and these can also be used in for bigWig files: http://genome.ucsc.edu/goldenPath/help/bigWig.html Let us know if you have further questions. -- Brooke Rhead UCSC Genome Bioinformatics Group On 1/23/12 8:33 AM, Alberto Ronchi wrote: > Hi Brooke, > > Thanks, this was very very helpfull. > I solved part of my problem (loading many tracks) creating the meta file. > I only have one question left: can i load a session file (custom made to match > the tracks loaded in the meta file) with the meta file itself?
