Smoothly change level of density map in animation?
Is there any way to alter the density level in a gradual fashion during an animation? I would like to first show the overall envelope of a cryoEM map, and then smoothly change to a higher contour level where I can see helices etc. Many other parameters, such as the presence of a MSMS surface or the position of a clipping plane, seem to automatically gradually transition between two key frames of an animation, but density level doesn’t seem to do so. Oliver.
Hi Oliver, The animation timeline has limited capabilities and is useful for very simple movies. To make any fancier movie you use a command script and movie command. The perframe command can vary a map threshold level perframe "vol #0 level .1 level $1" range .1,.02 frames 100 as illustrated on the movie command examples page http://www.cgl.ucsf.edu/chimera/data/movie-howto-mar2012/movie_examples.html <http://www.cgl.ucsf.edu/chimera/data/movie-howto-mar2012/movie_examples.html> Tom

Right, I see - thanks Tom. I haven’t explored the movie scripting too much yet, I will have to have a play with it. Oliver.
