[gmx-users] Measure contour area of bilayer undulation

[Hwankyu Lee]

Dear gmx-users,

This is not a question about Gromacs, but I wonder if I can hear 
suggestions from here. I would like to measure contour area of bilayer 
undulation.  If there is no undulation, area (area per lipid) can be 
easily calculated by dividing XY area by number of lipid.  But, in the 
lipid bilayer with undulation, how can contour area (ultimately, area 
per lipid) be calculated ?  If there are some suggestions about 
possibilities in Gromacs or other tools, it'd be really appreciated.
Thanks,

best,
Hwankyu.
