Depends on what you really mean by "size 16 A": you could hardly fit a
protein into a 16 Ang box if you want any reasonable distance between
the protein and the edge of the box.

An RMS shift (vs. what? an x-ray structure, a minimized structure?) of only
0.4 Ang. is unusually small. You may worry that fluctuations are being
underestimated for some reason. But this is speculation since I know
almost nothing about your simulation.

You should have no difficulty in finding hundreds of papers that describe
such simulations.

...good luck...dac
