[PyMOL] sphere_scale problem

[Vladimir Potapov]

Hi everyone,

I need to set different sphere radius in my task - large CA and small CB 
atoms. I use commands:
set sphere_scale=1.5, name ca
set sphere_scale=0.5, name cb
What I see, that command affects all atoms, not just those I want. Could 
anyone help with this?

My PyMOL version is 0.97.

Thank you,
Vladimir
