[gmx-users] lipid order parameter

[Pedro Alexandre Lapido Loureiro]

Hi,
 
I am confused!
I am simulating a DPPC bilayer and using g_order to calculate the order
parameter (Scd).
g_order output gives 13 Scds. DPPC has two chains, each with 14 CH2 groups and a
terminal methyl.
So, do those 13 values refer to the first 13 CH2 groups?
(My guess is that they refer to the last 13, based on comparisons with
experimental results.)
By the way, my index files (sn2.ndx or sn1.ndx) contain the 14 CH2 plus the CH3
groups.
 
Thanks,
 
Pedro.
