Hi Elaine, for a small demonstration, I want to make a movie in chimera where I animate a change in contour level. I have an EM map with noisy features that improve upon changing the level. I can do it by hand in the volume section but I cannot figure out what parameter it is even if I wanted to set it on the command line. Setting it on the command line I suppose would be the first step but then my question is: can this parameter be changed during an animation? Thanks, Lothar
Hi Lothar, Yes, you can use the “volume” command “level” option to change the contour level. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/volume.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/volume.html#general> The “volume” command doesn’t itself have frames option, but you can combine it with the “perframe” command to perform a gradual change in a single line, as illustrated with this video mini-example: <http://www.cgl.ucsf.edu/chimera/data/movie-howto-mar2012/movie_examples.html...> We generally encourage emailing questions to chimera-users (CC’d here) unless they involve private data, since others may like to know the answer. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco
