[chimerax-users] Depicting residues as spheres and adjusting sphere dimeter

Help will be much appreciated. I’m trying to depict residues as spheres of reduced dimeter. My commands are: select <help:user/commands/select.html> :9,11,33,38,49,50,51,52,53,64,65,66,101,105 117 atoms, 114 bonds, 14 residues, 1 model selected show <help:user/commands/show.html> sel style <help:user/commands/style.html> sel ball Changed 117 atom styles style <help:user/commands/style.html> sel sphere Changed 117 atom styles size <help:user/commands/size.html> sel ballScale 0.2 Changed 1 ball scales Likewise with: setattr <help:user/commands/setattr.html> m ballScale 0.3 create true Assigning ballScale attribute to 1 item Obviously the above commands are wrong as they fail to generate the desired effect Have a good day George
