Hi all, 
    this may be a trivial query to you. I want to calculate the area of lipid molecule. I have searched in gmx-archives and found how calculate the area of lipid molecule with respective Time(ps). I would like to ask two questions 
 1. Why we are concerning about (Box-x * Box-y)/(lipids of monolayer), why cant Box-z? 
 2. Box-x and Box-y means length of simulation box, if we increase the length of box sizes in x,y and zaxes for the system with 200 lipids(both sides) in that case is it possible to get simulation value near to experimental value 0.63nm^2/sec for POPC.

Thanks in advance.
