**What it does**

The heatmapper visualizes scores associated with genomic regions, for example ChIP enrichment values around the TSS of genes. 
Those values can be visualized individually along each of the regions provided by the user in INTERVAL or BED format. 
In addition to the heatmap, an average profile plot is plotted on top of the heatmap (can be turned off by the user; 
it can also be generated separately by the tool profiler). 
We implemented vast optional parameters and we encourage you to play around with the min/max values displayed in the heatmap as well as 
with the different coloring options. If you would like to plot heatmaps for different groups of genomic regions individually, 
e.g. one plot per chromosome, simply supply each group as an individual BED file.
