No problem, thank you for your response Tom ! Have a great day Enrico Il giorno mar 5 mar 2024 alle ore 01:36 Tom Goddard <goddard@sonic.net> ha scritto:
Hi Enrico,
The wait command needs the number of frames to wait when used with the coordset command. For a few other commands (turn, move, roll) the wait command can be used without any arguments and it waits until they finish, but that is only for a few commands and does not work with coordset.
Sorry for the delayed reply. I think you sent this question a few weeks ago but it did not get delivered until today due to problems with our mailing list software.

Okay, thank you very much Elaine !
Actually I tried to decompose my question regarding the automatization of the movie recording in ChimeraX.
For example if I do the following script:
# MAKE MOVIE WITH CHIMERA-X # start recording movie record size 3840,2160 supersample 1 # play reverse movie: from the end to beginning coordset #1 -1,1,-1
# encode the results movie encode format h264 quality highest output /home/enrico/PRIVATE/test_movie.mp4
so If I execute this script, the chimera-X will sends me an error that there are no frames to encode since it tries to run all commands at the same time. Alternatively I may add WAIT just before the movie encode, but in this case I need to explicitly define the period (e.g. wait 20).
Would it be possible rather to insert this pause w*ithout the** explicit definition of the period* (untull he coordset reaches the first frame ) ?
Many thanks in advance
Enrico

You could just try it to see for yourself, but yes and yes.
As described in the help: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/coordset.html>
coordset #1 -1
...goes to the last frame, so your commands act as you describe.

Just to precise ::
Coordset #1 -1,1,-1
Would this play the movie backwards from the last to the first frame ? ( so in this case I do not precise explicitly the number of the last frame)
Alternatively
Coordset #1 1,-1,1
Plays the trajectory from the beginning to the end , doesn’t it ?
Many thanks in advance !!
Le ven. 2 févr. 2024 à 17:14, Elaine Meng <meng@cgl.ucsf.edu> a écrit : Yes, you can simply use the "coordset" command to play the trajectory in reverse by specifying a negative step, e.g.
coordset #4 10000,1,-1
where as the help page says, #4 is the trajectory model number, 10000 is the trajectory frame to start, 1 is the trajectory frame to end, -1 is the step. Please see the page:

One more question about movie making in Chimera-X
Is there some possibility to record molecular movie in the reverse order from a given multi-model pdb file ? E.g. having 1000 models, I would like to record it from 1000,999,998 ... 1 .
Many thanks in advance
Enrico
