Add columns names over an heatmap

[Camille B]

Hello,

I just started to use ete2 and the heatmap drawer. I attached a matrix which contains presence/absence information for each of my leaf (in row) and for differents genes (in columns). The heatmap drawer works perfectly but I would like to now how to add the labels of the different columns over the heatmap.

Thanks

Hi Camille, 

sorry for the late answer. ClusterTree has a built-in heatmap mode that does *not* allow for column headers. 

However, there is an easy way to create your own custom heatmaps, which will give you full control of the tree image. 

I attach a commented example that creates a heatmap tree with column headers and custom color gradients. 

hope it helps
