Lately, I have waisted quite a lot of time trying to integrate bigWig files into GBrowse.
At first, I had problems with installation of Bio::DB::BigWig in Ubuntu 14.04 x64. I had to combine tips from several places (this was the most helpful):
wget http://hgdownload.soe.ucsc.edu/admin/exe/userApps.v310.src.tgz tar xfz userApps.src.tgz cd userApps/kent/src/ # in inc/common.mk replace `CFLAGS=` line with `CFLAGS=-fPIC` cd lib/ make cd .. sudo -i export MACHTYPE=x86_64 export KENT_SRC=`pwd` cpan Bio::DB::BigWig
Then, I have spent quite a lot of time trying to incorporate multiple bigWig files at once. This can accomplished with Bio::DB::BigWigSet. Just add this to your genome.conf:
[RibosomalRNASeq:database] db_adaptor = Bio::DB::BigWigSet db_args = -dir /path/to/your/bigWig/files -feature_type summary [All] database = RibosomalRNASeq feature = summary glyph = wiggle_density height = 15 category = Ribosomal RNA-Seq
Note, your bigWig files should be placed in one directory and end with .bw.
Additionally, you can create meta.bw file that will define additional information about your samples.
