Hello and thanks a lot for the quick comments!
Thats a good idea I also considered but was held off by the thought that frames are more flexible. Thanks for clearing this up. Actually, one could say that the topology is the same for all frames, as nothing is specified apart from graphics primitives (thus 0 atoms and so on). The coarse-graining thus is just painted to be able to overlay it with the pdb structures later on.
Thanks for mentioning the plugin, Ill look into this solution.

It would be great if the concept of frames was made more abstract, basically serving as a canvas for whatever to display.

Be well,

Apart from "animate dub" I couldnt find anything, but using this, all 
frames are the same (either all animation frames painted above each 
other (if graphics primitives are not deleted) or just the last one (in 
case on each frame the primitives are deleted).

Maybe there is a very very simple solution to this to make VMD a very 
flexible animation tool?

yes, the solution i would suggest, is to create multiple "molecules",
draw into them and then show only one of them. check out the
multimolanim plugin as an example for that. this was created to work
around the limitation of VMD that all frames have to have the same
topology data, but it should work for you just as well.

in case of mpeg generation, you have to use the "user" function method
and supply a function that toggles the display between multiple
molecules. you can probably "steal" the guts of that function from


Thanks a lot,
