Hi Dmitry, If you mean to move by hand (e.g. with mouse/trackpad), see mouse modes "translate selected atoms" and "rotate selected atoms": https://rbvi.ucsf.edu/chimerax/docs/user/commands/ui.html#mousemode https://rbvi.ucsf.edu/chimerax/docs/user/tools/mousemodes.html

Actually if you turn on either one, modifying with Shift does the other one. E.g. if you assign right mouse to "translate selected atoms," then right mouse + Shift will rotate selected atoms.

There is also a "bond rotation" mouse mode to rotate the clicked bond, see the links above.

If you mean with commands, you can do it with the "atoms" option of many movement commands (turn, move, etc.) https://rbvi.ucsf.edu/chimerax/docs/user/commands/turn.html https://rbvi.ucsf.edu/chimerax/docs/user/commands/move.html

There is also a "torsion" command to rotate bonds. https://rbvi.ucsf.edu/chimerax/docs/user/commands/torsion.html

I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Dear colleagues,

Is there a way I can move(rotate) the chain/residue within a model in ChimeraX?

If yes, then how?

Thank you in advance.

Kind regards, Dmitry
