-Contacts are a useful tool to analyse protein structures. It simplifies the 3-Dimensional view of the structures into a 2-Dimensional set of contacts between its atoms or its residues. The representation of the contacts in a matrix is known as the contact map. Many protein structure analysis and prediction efforts are done by using contacts, see for instance
