[gmx-users] dihedral angles

[Milan Melichercik]

Hi
I have simulation of phospholipid menbrane and I need to calculate trans 
fraction as a function of position of dihedral angle in lipid chain (I means 
that the points on x axis will be - (dihedral between C1A,C1B,C1C, C1D as a 
1st point; dihedral between C1B,C1C,C1D, C1E as a 2nd point; etc.).
I alse need to calculate the transition time as a function which depend on 
same thing as the function above. But I don't know, how to compute it (I 
suppose I sould use a g_angle).
Thanks for an advice.

ps: if it is not clear what I meaned by X axis, I can send a picture with 
similar graph I need.
