smoothing of wiggle_xyplot with BAM database

Matthew Hobbs

I have some tracks which show coverage of some NGS data stored in BAM format (see configuration excerpts below). I would like to see what the coverage looks like with some smoothing but can't make this happen. The wiggle_xyplot's "smoothing" and "smoothing_window" options don't seem to have any effect on what is produced - should they?  I see in the Bio::DB::Sam documentation that it is possible to calculate  coverage across larger bins by using e.g. "coverage:500" but how do I do this from within the gbrowse configuration file, where "coverage:500" is used for semantic zooming?

I am using Bio-SamTools-1.14, Bio-Graphics-2.02, Generic-Genome-Browser-2.03

Thanks for any help,
