Hi Stefan, You could try opening one session (the one whose viewpoint you want to use for both), and using "matrixget" to save the transformation matrix to file. E.g. on my mac I could use: matrixget ~/Desktop/mymatrixfile Then close session, open the other session, and use "matrixset" to apply the previously saved transformation: matrixset ~/Desktop/mymatrixfile See description of these commands: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/matrixset.html> I hope this helps, Elaine ----- Elaine C.

Hello, I have two Chimera sessions which originate from the same pdb. Through rotations and movements the sessions viewpoints diverged over time. Is there a way to synchronize one session with the other so it has the exact same viewing angle? Thanks Stefan
