I’ve issued the following commands for my models

select #2/A:120,119,41,36,37,34,49,117

72 atoms, 68 bonds, 8 residues, 1 model selected

setattr m ballScale 0.2 create true

Assigning ballScale attribute to 2 items

No changes were observed on the ball scale. Is it likely that I should be trying something different to change the ball diameter?

Thank you
