Dear Anabel,

As others pointed out, you can just represent the beads as balls, points, or wire, and remove all the pseudbonds.

On the other hand, how did you obtained your pdb? If you used GNOM in the ATSAS package (GUI version), it writes pdbs with a bigger bead size, which Chimera fails to represent by default. But if you use GNOM in the command line, it writes pdbs with a smaller bead size, which are more compact, smoother, and better for representation in Chimera, and others.

Best,

Yasser

Dear Chimera team,
I am a user from your software and I would like to have a
superimposition of some crystallographic structures in a recent saxs
pdb model I obtained. However, I cannot visualize the saxs pdb file
with Chimera. Would you have any tips or inputs how can I do this?
Thank you very much in advance for all your help,
Kind regards,
Anabel
