[PyMOL] changing individual sphere sizes

[L. D. <du...@ia...>]

Hello, 
I need to have  spheres or dots of different sizes on a RNA ribbon. We are
trying to show that residues modify at a smaller or larger extent. So, I need to
have at different places differently sized spheres. 
Hopefully I was explicetly enough. 
Thank you, 
Laura
