Hello,

I'm a freshman to ChimeraX. I'm building an atomic structure of a synthetic peptide-like compound, following the online tutorial, https://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html#start

I copied a SMILES string from the SMILES translator, and it gives a structure. Very good. But I want to adjust some bond angles. But I can't find the Adjust Torsions section in the dialogue of Build Structure (see the screen-print below). I can't active it by using the "rotation" command either, even though the target bond is already selected.

Would you please help me to figure out this?

Best regards,

Haiqin DU
