Thank you for the prompt reply Elaine. I hadn't spotted this link even though I had rummaged through Chimera help. </div>

The scripts look very useful. But I'm not sure where they woud be run..these don't look like Chimera command line instructions? The first line seems very unfamiliar...perhaps "Pett" might elucidate? Or one of your colleagues if you are also uncertain about
their use?</div>

Hi Simon,<br>
Thanks for introducing others to Chimera!<br>
<br>
I'm not the expert on this topic, so I had to consult with others to answer this question. Just as a reminder, it's recommended to send questions to chimera-users@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.<br>
<br>
RMSD compares different sets of coordinates, so I don't think that gets you anything like the radius of gyration of a single set of coordinates.<br>
<br>
There are some scripts to calculate radius of gyration on the Chimera Python Scripts page:<br>
<<a href="https://plato.cgl.ucsf.edu/trac/chimera/wiki/Scripts">https://plato.cgl.ucsf.edu/trac/chimera/wiki/Scripts</a>><br>
<br>
I hope this helps,<br>
Elaine<br>
