After poking around the chimera-users archive after googling it for "radius of gyration" I recommend looking at these previous posts (and possibly others in their threads, but these seem to be the most important):
I hope this helps,

Just as a reminder, it's recommended to send questions to chimera-users at cgl.ucsf.edu (CC'd here) unless what you are sending needs to remain private. I don't know everything (surprise!) or I might not understand your question as well as somebody else does.
