We have a number of resources available for hinge analysis.
StoneHinge: StoneHinge is a hinge prediction algorithm that performs a network-based analysis of a single protein structure to detect hinge regions. StoneHinge incorporates both ProFlex, which uses the FIRST constraint counting algorithm, and DomDecomp, which uses Gaussian Normal Mode analysis.
HingeMaster: The new HingeMaster server predicts hinge locations in single protein structures. The algorithm combines FlexOracle, TLSMD, StoneHingeP and NSHP hinge predictors for maximum accuracy
RigidFinder: performs comparison of two protein conformations with the aim of identifying movable rigid regions.
