[Chimera-users] pause during morph conformations

[Elaine Meng]

Hi Charles,
It can be done with commands.  First you would create the morph trajectory, then use a Chimera command script (just open a plain text file containing the commands) of the general form:

movie record [options]
coordset 1,20 #3; wait 20
wait 10
coordset 21,40 #3; wait 20
wait 10
coordset 41,60 #3; wait 20
movie stop
movie encode [options]

where [options] is not meant literally but would give your desired movie settings, and you would also change other things depending on which model is your trajectory and which frames cover the transitions, and how long you would like the pauses to be.  I would also recommend saving the session with your morph trajectory in the desired orientation so you can revisit it later and easily re-make the movie with any needed variations.

There is an example command file showing a similar procedure...
the "trmovie" example includes morphing and uses coordset to play parts of the trajectory and does other stuff between the uses of coordset (it actually does the morph creation too, but it may be easier for you to do that part beforehand):

... and the resulting movie is in the Animation Gallery, currently third on this page:

I hope this helps,
