Hi Andy, I'm sure there are different ways of doing it, but the general approach that comes to my mind is: - get or build the structure of the whole filament with as many subunits that you want to have at the end of the movie, where each monomer is either a different chain or a different model. Maybe that's the hard part? If you don't already have that, maybe you can make it with "sym" but the tricky part might be specifying the correct center, axis, etc. of the symmetry to build the whole thing. - hide the parts you don't want to show at first (either specific model #s or specific chain IDs) - save as session so that you can keep working on the movie script. E.g. just open session, run script, modify script as needed. - in your movie command script, include commands to keep showing additional subunits. You could do other stuff at the same time, like rotate, zoom, show 2D labels. Don't bother to add the movie-recording commands until the script shows what you want to have in your movie.

Dear All,

I am trying to make a movie where I can show the atomic model of the subunits appearing one after another following the helical pattern forming the filament.

How can I do that?

Stay safe & Regards
