Graphical proTRAC output. Standard visualization (top) and customized visualization of the same cluster with indication of transcription rate and highlighting (red) of multi-copy loci (bottom). Sequence reads mapped to the plus-/minus-strand are directed upwards/downwards of the center line respectively. Upper coordinates refer to the length of the cluster, lower coordinates refer to the location of the cluster on the respective chromosome or scaffold.
