Subject: AMBER: dihedral calculation problem

Dear All,
 I use the "dihedral" command to do the calculation. I am just wondering how to define the negtive and positive angle value in the Ptraj program. Since in my calculation, these 2 dihedral angles should be in the diferent direction, it means one prefers negtive value, the other one is opposite. But from my calculation results, it is almost the same, I mean both of them are positive. Is there someone know how to make it in a correct way? Thanks a lot!
