[Chimera-users] Chimera movie with simulation time labels ?

It may be possible using per-frame scripting in MD Movie (in that tool's menu: Per-Frame... Define script). I've definitely shown frame number as a label for a trajectory, details below.
The process would be something like:
- figure out equation to convert frame number to time
- per-frame script would use that equation and show result as a 2D label
- record movie while the per-frame script is active
I think it would be necessary to do it in Python, to include the equation part, but the script dialog provides a way to use frame number in the script. The only part I am concerned about is whether the equation output (simulation time) has to be converted to a character string to be used as label contents.
I have definitely used this process to simply show the frame number as a label during the trajectory. That is done with a per-frame script of Chimera commands in the "Trajectory and Ensemble Analysis" tutorial, part 1:
I hope this helps,
