[chimerax-users] Morphing animation

[Elaine Meng]

Hi Daniel,
Coordset is for replaying a trajectory.  If your series of structures is indeed a trajectory, it is not in the form of submodels #3.1-51 (which could all be shown concurrently) but instead just #3 where only one trajectory frame can be shown at a time.

I.e., if "coordset" works to replay your trajectory, then you just need to have #3 in your perframe command, not #3.$1 -- I'm guessing that is the problem.

If your series of structures is not a trajectory but a series of submodels, it is not a trajectory, and instead of "coordset" you would need to play through it with "mseries":

coordset:

mseries:
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/mseries.html>

trajectories and model series:
<https://rbvi.ucsf.edu/chimerax/docs/user/trajectories.html>

I hope this helps,
Elaine
