Hi,
If what you're interested in are atomic fluctuations you can use the
'atomicfluct' command to calculate them within each reference frame.
See the manual for more details.

I'm interested in this one domain and somehow looking at the difference between overall fluctuations and fluctuations with this one domain. It seems like the way to do this would be to subtract the two and analyze the difference trajectory. I have not been able to find a way to do this yet.
