DESCRIPTION
gmx sorient analyzes solvent orientation around solutes. It calculates two angles between the vector from one or more reference positions to the first atom of each solvent molecule:
|
• |
theta_1: the angle with the vector from the first atom of the solvent molecule to the midpoint between atoms 2 and 3. |
||
|
• |
theta_2: the angle with the normal of the solvent plane, defined by the same three atoms, or, when the option -v23 is set, the angle with the vector between atoms 2 and 3. |
The reference can be a set of atoms or the center of mass of a set of atoms. The group of solvent atoms should consist of 3 atoms per solvent molecule. Only solvent molecules between -rmin and -rmax are considered for -o and -no each frame.
-o : distribution of cos(theta_1) for rmin<=r<=rmax.
-no : distribution of cos(theta_2) for rmin<=r<=rmax.
-ro : <cos(theta_1)> and <3cos(ˆ2theta_2)-1> as a function of the distance.
-co : the sum over all solvent molecules within distance r of cos(theta_1) and 3cos(ˆ2(theta_2)-1) as a function of r.
-rc : the distribution of the solvent molecules as a function of r
