Hi Chimera team,

  I want to make a figure of the protein highlighting the following features:

 - The whole structure is shown in cartoon

- The CA-atoms of some residues are highlighted as a sphere on top of the cartoon model.

  When trying to make that, the spheres are off in space and not exactly on top of the cartoon model. Is there a remedy for that?.
So the spheres appear on top of the cartoon rather than in empty space. Also, how to turn the bonds off between consecutive CA-atoms?

   Thanks for help,
  Ibrahim
