Hi Martin, Such work is in progress, and you can do some of what you describe, with the Animation tool and/or "scene" command in Chimera 1.7 (daily builds). You can save scenes and then transition between scenes. However, it is still in the early stages, and must be noted only simple transitions are available and that scenes make your session files very large. <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/animation/animation.html> <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/scene.html> However, there is already another well-established approach, much better than interactive manipulation: creating a Chimera command file that scripts all the motions, color/display changes, etc. For a long time, Chimera has allowed saving and restoring "positions" -- while these don't include colors, styles, etc. like scenes, restoring positions can be done in the Chimera command script along with other commands for the coloring and display. Several commands have "frame" arguments so that they can be applied gradually over a specified number of display frames. Chimera "making movies" documentation: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/movies.html> ... scripting movie content: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/movies.html#content> ... and from the above there are additional links to example script files and video mini-examples for Chimera 1.7 (you would need a recent daily build) I can't address the registration issue, the others will need to look into it. I hope this helps, Elaine ----- Elaine C.

Hi, I recently published a tomographic reconstruction that was rendered using Chimera (see:http://www.pnas.org/content/107/36/15676.abstract)

The movie that we were able to build using Chimera was excellent, but had to be recorded entirely in real time. That is, we had to turn on recording, manipulate the model, and turn off recording. I feel that it would be much easier if there was a nice interface to sequencing functionality. In this (as I imagine it) a sequence of particular views could be stored, and times specified for smooth transition from one element in the sequence (‘view’) to the next. These views could even be stored as saved sessions (if that helps with implementation).

Please let me know if this functionality is already possible and (if so) please send me a sample!

I note that my licence has expired; but when I try to renew it I run into problems with the server.

Looking forward to your reply,
