[gmx-users] How to make grids in lipid bilayer (to measure contour length)

[Hwankyu Lee]

Dear gmx-users,

I'm trying to calculate contour length of huge lipid bilayer with 
undulation (non-projected area per lipid). In order to calculate that 
accurately, I would like to measure contour length in local areas of 
bilayer by making lots of grids in lipid bilayer.  I'm wondering if 
there is a tool or way to make grids in lipid bilayer in the .xtc 
trajectories.

Thank you for your help in advance.

best,
Hwankyu.
