[Chimera-users] movie trajectory

[Elaine Meng]

Hi Jean-Paul,
I wanted to explain that many of the movie-related commands listed in

> http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/movies.html

have a "number of frames" argument.   For example, the command

roll y 1 360

performs a 1-degree rotation around the Y axis in each of 360 frames  
- you don't have to repeat a 1-degree rotation command 360 times!     
There are similar commands for scaling, translation, and  
interpolating between previously saved positions, as Eric  
mentioned.   The page also links to some example command files.
Best,
Elaine
