[gmx-users] what error!

[chiloo Laohpongspaisan]

Dear all,
 
i have got the abnormal values of torsion angle by using g_angle of gromacs.
 
g_angle -f whole.xtc -s md.tpr -n index.ndx -ov out_avrg.xvg -od out_dist.xvg -type dihedral
 
i use such tool in many systems, the torsions along time seem to be normal except one. And the values are as below.
   0.00000   114.224
   0.50000   148.269
