Hi Laura,

You can change the van der Waals radii of atoms using

alter selection, vdw=newradius

Alternatively, you can use the setting sphere_scale (set sphere_scale,factor), which changes all radii by the given factor. Note that you need to create different objects to use different factors for sphere_scale.

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,
