[gmx-users] Position of a molecule in a bilayer

[Rama Gullapalli]

Dear GMX ers
 I would like to compute the position of a small molecule inside a lipid bilayer as a function of its position along the Z axis. Which GMX program is best suited for this?
 
 I tried using g_traj, but I got some weird results when i computed the COM position of a DPPC molecule. The COM position of DPPC was crossing the center of the lipid bilayer which is weird.
 Thanks
 Rama
