{wiki=Direct_coupling_analysis}
Direct Coupling Analysis (DCA) is a computational technique used in various fields such as biology, particularly in the analysis of protein structures and interactions, as well as in machine learning and statistics. In the context of protein science, DCA is used to identify and model the interactions between different residues in a protein sequence. The primary goal is to discern which amino acids are directly coupled to each other through evolutionary relationships.
