[Chimera-users] adding morphs to scene animation in Chimera

Hi Mike,
You would first create all the morph trajectories of interest, then for each morph, create a scene showing the first frame of the range you want to play and another scene showing the last frame of the range you want to play.  These scenes should also have the desired display styles, colors, etc. Then you add those two scenes as keyframes to the Timeline in the Animation GUI.  The transition between the two will proceed through the intervening trajectory frames as described under keyframe Duration in the Animation docs:

The other way to include morphing in an animation is to use a command script with "coordset" to play back the trajectories, with various other commands (instead of scenes) to change colors, styles, and orientations.  There are a couple of examples with command scripts in the Chimera Animation Gallery:

Kinase morph: 

Ball-and-socket motion:

Those only include one morph trajectory each, but generalization to multiple morph trajectories is merely a matter of having additional already-created morph trajectories (usually saved in a session), hiding one trajectory and showing another, and having additional "coordset" commands to play back the subsequent trajectory models.
I hope this helps,
