What it does

The extent to which the atomic fluctuations/displacements of a system are correlated with one another can be assessed by examining the magnitude of all pairwise cross-correlation coefficients. The DCCM Analysis tool can plot the atom-wise cross-correlations using the Bio3D package. Negative values (negative correlation) indicate the atoms move in opposite directions, while positive values (positive correlation) indicate the atoms move in the same direction.
