Sounds like your analysis program is broken and cannot properly handle periodic boundary conditions.

Subject: namd-l: Drifting water molecules
Hi,
When I run water on graphite simulation, my water bulk drifts towards next
cell, such that at the end of the simulation I have part of the water in
one cell and part in another.
I have to do an analysis of the trajectories and the program I use does not
read the part of the water molecules that are in the adjacent cell.
What can I do to keep  all water molecules centered in one cell, such that
my program can read all trajectories?
Thank you,
Mihaela
