How to make the final heatmap normalized with total reads

[Honkit Wong]

Thanks for the great tool!

In the methods, I read "Normalized data are used only to perform the clustering step but raw intensity data are displayed in the final heatmap to recover the original patterns from data".

I wonder if there's a way to display the final heatmap as normalized by total reads, as it is very often that ChIP-seq will general different number of total reads. Really want to use the normalized heapmap image for my publication. Thanks!!
