Hi Elaine, I'm trying to make a movie using Chimera. The basic outline is as follows: a homo-dimer is dissociating into monomers, then focus on one of the monomers rearranging into a compact form. I think I could record the dissociation step with "savepos/fly" option, and morphing works for the second step. Is it possible to stitch them together for a single QuickTime file? Thank you for your time, Vlad Kuznetsov (Sacchettini lab, Texas A&M University)

Hi Vlad, Instead of combining two movie files into one movie file (it must be possible, but I don't have experience with that), I would just do everything in one Chimera movie content script. You could either do the savepos and morphing in the same or a different script before starting recording, or do it interactively and save the session. Then restore session if you had saved a session, and execute your recording script, in which you can use fly and other movement commands (move, turn, ...) as well as the coordset command to play the morph. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/movies.html> There is an example movie and associated Chimera script in the Animation Gallery, see "Ball-and-socket motion" currently the 6th one down: <http://www.cgl.ucsf.edu/chimera/animations/animations.html> I cc'd chimera-users@cgl.ucsf.edu since this answer might help others (it's generally better to send questions there than to me directly, unless you are including private data). Good luck with making a beautiful movie! I hope this helps, Elaine ---------- Elaine C.
