[gmx-users] P-N vector orientation

[ANINDITA GAYEN]

Dear Xavier Periole  


                    
I am a GROMACS user, presently working with DMPC  bilayer. I want to calculate the orientation of the head groups
P-N vector. From gmx-users,  I have came to know that you have a
program that can determine the angle of the PN vector (or what ever
pair of atoms) relative to the z axis. 



If possible, can you please provide me that program or tell me how can i calculate that?







Thanks in advance.
