Thanks Axel. This sounds like a good idea, but I am not sure how I would
superimpose a single snapshot (of just the text labels) onto the frames of
the Tachyon-rendered time-bar and protein - i.e. just superimposing the text
and not the plain white background. Is there a command for ImageMagick that
will do this?
