[gmx-users] Reg:Density Profile

[vinothkumar mohanakrishnan]

Hi all,

I have a system composed of DCE and Water in a 2.17x2.17x4.9800 simulation
box with an dce-water interface.I want to investigate the density profile of
the system, and  I used the following command line to do that:

g_density -f traj.xtc -n index.ndx -dens number -sl 100

The density profile for the two types of particles looks OK except the
boundaries of the simulation box. I mean I would not expect to get a number
other than 0 at the lower and upper boundaries. I have also searched the
mailing list. There was an e-mail similar to that one, but it was not
replied.

I have attached the density profile in the attachment.

Why is it the case?
