[chimerax-users] Problems adjusting the phi/psi angles with ChimeraX

Dear ChimeraX team, I was trying to use ChimeraX to change the phi/psi angles of a residue in the loop region but encoured this error: ILE 411 N ↔ CA is part of a ring/cycle and cannot be rotated. There is no ring/cycle in ILE411 or neibouring residues: ASN 410 or THR 412. I tried ChimeraX daily (version 1.10.dev202504260127 (2025-04-26) and ChimeraX 1.10.1 but the same error happened. I am wondering if it is possible to change the phi/psi angles with ChimeraX. Thank you. Best, Zhen
