[Chimera-users] Morphing with two models

Hi Enrico,
Any Chimera actions can be done with python, but I can't give advice  
on that (I don't know python).  To me, it seems much easier to use a  
few Chimera commands than to figure out the python to do the same  

 From what you said, now I think maybe you are making a movie, not  
just trying to superimpose structures to prepare for morphing.  In  
that case, here is how you could easily achieve complicated motions  
of multiple models:  use the command "savepos" to save different  
positions, say one position with the models together and another with  
the models apart.  Then you can use the command "reset" to go between  
these saved positions in a specified number of frames.  Depending on  
those previously saved positions, the (two or more) models could go  
in opposite directions.

For movie making, I recommend using version 1.4 of Chimera (a daily  
build) because many of the  movement commands have been improved  
significantly since the last production release.


I hope this helps,
