Dear Amber users,
I want to calculate the time autocorrelation function of a dihedral angle.
I've used dihedral command from cpptraj to get the angle. For instance:
dihedral theta .Si6 .C18 .C20 .C24 out theta.dat
Command timecorr requires a vector as input, so I guess my question is how
do I translate dataset theta into vector set (cos(theta), sin(theta), 0) so
that I can feed it to timecorr.
Related question: with output file theta.dat I can create file vector.dat
with columns cos(theta), sin(theta), and 0. Then is it possible to read
file vector.dat into a vector set that I can pass to timecorr?
Best regards,
-Jose Borreguero
