[Chimera-users] Scripting commands for existing morph

Definitely, this is a very common situation of scripting movie content that includes playback of an existing morph trajectory. The playback part would be done with the “coordset” command, and there are several additional movie-related commands, as listed in the “making movies” page:
Further, the Chimera Animation Gallery has some movies with morph trajectory playback, and includes the command scripts that were used to create them:
(1) Kinase morph, Chimera session kinase-morph3.py with already calculated morph, Chimera command script kinase-morph3.com
(2) Ball-and-socket motion of thioredoxin, Chimera command script trmovie.com (includes morph calculation)
This should cover what you want to do, and more. I hope this helps,

Then interpolate (morph) to the other endpoint (second structure) for x number of movie frames and then wait again for a specified number of movie frames. Or even more complicated rotate the molecule or superimpose something else while it is interpolating/morphing between the pdb coordinates.
