Dear all,

I am simulating a binary system of two non mixing components (5CB and water using version 4-0-3; the whole equilibrated trajectory is about 300ns). 
I want to calculate the rdf of the centers of mass of 5CB using the command 
g_rdf -f traj300.xtc -rdf mol_com  -o rdf_com_300.xvg -noxvgr.
The problem is that the rdf I am getting does not approach zero at long distances. Is there a way to correct that?

Thank you in advance for your help,
