I am analyzing how the force in residue ABC is propagated and affected by
the neighboring residues DEFG...like, the motion between residue ABC and
residue DEFG...
if force-force time correlation function seems usable, I want to try this
action,
it is the command typed:
> force-force time correlation or other more specific commands?
thanks
