Project description
Hclust2 is a handy tool for plotting heat-maps with several useful options to produce high quality figures that can be used in publication.
Installation
$ conda install -c bioconda hclust2
Examples
Below is the heatmap produced by Hclust2 on the MetaPhlAn2 abundance profiles of HMP and HMP1-phase2 samples (microbial species and samples are hierarchically clustered).
