FMA (Functional mode analysis) is a technique to identify collective atomic motions related to a specific protein function. Given a large set to structures of one protein, for example from a molecular dynamics trajectory, the method detects a collective motion (or collective mode), that is maximally correlated to an arbitrary quantity of interest. In other words, the method aims to explain alterations in a quantity in terms of internal collective motions of the protein.
