What is a heat map?

Here's a short video explaining how heat maps are built in an OMICs world, and what kind of information heat maps provide. Everything is explained through a mini - tutorial using the OMICs module of the XLSTAT statistical software for Microsoft Excel.

We are very grateful to the PAPPSO platform (Gif-Sur-Yvette, France) which provided the dataset, which was used in a paper published in Proteomics:
