[Jmol-users] tying echoes to sets of frames

[Frieda R. <fri...@ma...>]

Hi Bob et al.,

I would like an echo to appear at the top of the frame during frames 1-10 of an animation, then a different echo to appear in the same spot for frames 15-25, and a third for frames 30-35. I’ve been looking at 'set echo' in the script doc, where I see:
> Echo text can be associated with a specific model, with visibility controlled by the frame command. See below.


and then below (as advertised)
> set echo id MODEL (model number)
> By default, when multiple models are present, all echo text is visible regardless of the model currently displayable using the frame command. The set echo ... MODEL command associates an echo with a specific model, allowing the text or image to appear and disappear when different models are displayed using the frame command.

I have tried many different permutations of this without success.  I am clearly misunderstanding something, possibly several things… Can someone point me in the right direction? What would a simple example command look like?
