Dear Caroline, I'm not sure why your command
move x -1 10 atoms /A; move x 1 10 atoms /B
doesn't work... maybe there is a bug in the parsing of this syntax, or maybe the documentation needs to be revised. We will need to take a look at that. However, you can accomplish this gradual translation of the two chains in opposite directions by combining "move" with "perframe." I tested the following in ChimeraX 1.6 just now and it works: perframe "move x 1 atoms /A; move x -1 atoms /B" frames 10 I hope this helps, Elaine ----- Elaine C.

Dear ChimeraX team and list subscribers,
I am making a little movie to show a complex of two proteins, but am stuck on individual movements of chain /A and /B.
If I use the move command, chain /A and /B both move independently, away from each other: move x -10 atoms /A; move x 10 atoms /B
However, if I attempt to do the same movement by going -1 or +1 over a series of 10 frames, I no longer get any movement of /A and /B. move x -1 10 atoms /A; move x 1 10 atoms /B
I can achieve movement over a number of frames, but both chains move although I tried to specify only /A. I did this based on "move axis [ distance [ frames ]]". move x -1 10 atoms /A
I feel I might be on the right track because when I use turn, I am able to trigger simultaneous independent rotation of /A and /B around their own axes (thank you for this feature by the way, last time I wondered about this it wasn't possible). cofr /A; turn y -1 90 atoms /A; cofr /B; turn y 1 90 atoms /B
My ultimate goal is to open the binding interface up a bit like opening a book. I suppose I could achieve a similar effect by setting the centre of rotation for each chain behind, rather than within - if independent movement over a series of frames isn't possible, I might experiment with that.
I updated to version 1.6 and searched the list, but I still see this behaviour with the move command. Perhaps I am missing something basic?
Thank you for any pointers you might be able to share! Caroline
