[chimerax-users] circular balls instead of residue

[Elaine Meng]

Dear Revan,
Works for me:

open 1gcn
show :10
style sphere
size atomRadius +1

Tested using ChimeraX version 1.5

You would use the "suppress false" option of ribbons/cartoons if you want to show backbone atoms at the same time as the ribbon, for example to show 1zik chain A residues 2-12 alpha-carbon balls:
