Hi,
You want the 'correl' keyword for the 'matrix' action in cpptraj. (I
guess I should make 'dccm' an alias for that...)
From the manual entry for the 'matrix' action:
```
Calculate a matrix of the specified type from input coordinates.
dist: Distance matrix (default).
correl: Correlation matrix (aka dynamic cross correlation).
```
Hope this helps,
-Dan
