Subject: AMBER: question about dihedral angles

Hello,

I noticed that in the force field file, in dihedral angle part, for example,
there are entries like:
X - CT - OS - X 3 1.15 0.0 3.
CT - CT - OS - CT 1 0.383 0.0 -3.
CT - CT - OS - CT 1 0.1 180.0 2.
So, when assign the parameters to dihedral angle CT - CT - OS - CT to
calculate the energy, are all three entries used or just the latter two
used? Thank you.
