[galaxy-dev] UCSC genome browser

Dear Developer my institute would like to run a local version of Galaxy and I managed to properly install it on my mac. We are focused on plant and especially on Arabidopsis. I managed to upgrade our local Galaxy with Arabidopsis genome and I am able to run some analysis (ChIP-seq) from mapping to peak detection with MACS. The next step would be to visualize the results on UCSC genome browser. We have a local version of it (with the latest Arabidopsis genome assembly) but MACS result hasn't got any link to UCSC GB but only to GeneTrack (that is not working). How can I make Galaxy aware of our local GB? thank you very much kind regard r
