Hi There, Is there a way to color reads by their Read Group in AlignmentTrack in Gviz? It can either be in the stacked view or the coverage histogram (preferred). My data comes from a multi-sample BAM file, with Read Group information for each read.

I could achieve this in IGV (see right pane below)

In addition, can I add the chromosome name somewhere on/next to the GenomeAxisTrack?

Many thanks, Ido
