[PyMOL] Radius of gyration of a trimer

[Dr. S. S. K. <sen...@hu...>]

Hello, 

I would like to measure radius of gyration for a protein (1JB0). The PDB
structure is only a monomer. But, I would like to find the RoG for the
trimer. Could any one please help me? Bytheway, I failed massively even
to get RoG for monomer and it says 'RoG is not defined'. I would
appreciate your time and effort. 

Thank you. 

Best regards, 

Senthil
