Subject: [gmx-users] the radius of dry core

Dear GROMACS Specialists,

I am working about micelles and have a question about the radius of dry core.
May I ask you to answer me, Please?
In one paper, I saw that the radius of dry core equals where the density 
profiles of water and the surfactant hydrocarbon tails cross and a fraction of 
about 0.78 methylenes are found to be within this distance to COM.
I don't know how I obtain the fraction of methylenes in this distance to COM!
Please help me.

Thank you very much in advance.
Best Regards
Dina

Dear Dr. Warren,

Thank you very much from your help, but I want to calculate the fraction of 
methylenes in this distance to COM. How do I obtain this fraction in this 
distance by RDF, Please?

Thank you again.

RDF = probability function

Methylene density (number in the box (Nt) divided by the box volume), 
multiplied by probability (RDF) and shell volume (r+dr) calculates number of 
methylenes (Nm) within a given shell.

Fraction = Nm/Nt
