[gmx-users] Cross-correlation Dihedral Angle

[atanu das]

Hi All,
I have a 1 microsecond trajectory of a 11-residue peptide sequence. I want to identify how the movement/change of one dihedral angle dictates the dynamics of the other ones (if any). I was wondering if there is a way to estimate cross-correlation matrix (something similar to what can be obtained by using g_covar for C-alpha atoms) for dihedral angles.
ThanksAtanu
