Ah yes, that is what I was looking for, something like: for (var i=1;i<100;i=i+1) save ORIENTATION movie load /tmp/file.xyz @i restore ORIENTATION movie delay 0.5 delay on end for But then less flickery :) By keeping the orientation the same during the loop, you can turn around the animation while it is playing, which is cool & practical. > >Or are there too many disadvantages to that (not being able to edit > >objects in frames that aren't read yet, long loading times per frame). > >I guess also a problem is that one cannot always assume that the atom > >types and order stay constant over the multiframe file. > > > > > > > Be more specific about your plans for that large file? Could it stream? Actually I mean as above, but streaming is also nice :) I remember that vmd can handle streaming data. Watching simulations in real-time seems to be one of those dreams of the 90s that never really caught on, though. > I've certainly thought about this.

That's in Jmol > now, but I haven't experimented with it much. If Jmol could do the per-frame reading in a fluent way, 'trajectory-mode' might not even be needed. Otherwise it's probably a good way to save memory while watching simulations in Jmol. -- Greetings, Pim http://www.molmod.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
