Hello,
I am trying to make movies from pdb-file trajectories where the
colors of the atoms are defined by the 'beta' index and are updated at
each step.
I can't get them to update at each step.

I found a previous posting about this problem but I couldn't find the
example
script mentioned in the reply (below). Do I need to learn
Tcl or is there a quick-fix ? Does anybody have an example script ?

Thanks for help,

Paul Tangney

P.S : Great program, by the way. I just started using it.
