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 !!
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:

I hope this helps,
