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. Elaine

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
