It’s also called a false colored image, where data values are transformed to color scale. Heat maps allow us to simultaneously visualize clusters of samples and features. First hierarchical clustering is done of both the rows and the columns of the data matrix.

Elastic networks. Distance geometry. Much structural information is encoded in the internal distances; a distance matrix-based approach can be used to predict protein structure and dynamics, and for structural refinement. Our approach is based on the square distance matrix D = [r ij 2 ] containing all square distances between residues in proteins.
