[Chimera-users] How to force Chimera to properly analyze and visualize in each MD movie frame the ribon representation of the protein structure ?

I just found that if one loads several frames from the simulation
(Amber prmtop + inpcrd, *.rst files) chimera calculate/set the character
of ribons (random colil, beta sheet, alpha helix) just using the first
loaded frame and even if structure of the protein is changing in the
next frames (e.g. forming beta sheet structure from the originally random
the visual ribon representation is not changed.
I found this, when I loaded just the isolated frame from the simulation and
saw nice forming of the local beta sheet which was nicely highlighted by
proper ribon representation (wide arrow) in the palce where was originally
(in the initial frame) just random coil. But when I loaded both (initial
frame and that after some MD simulation),
chimera keep to use random coil representation for both frames.
I did also reverse experiment i.e. first loaded later frame from MD
then the initial frame and this time chimera fixed for both frames beta
in that protein area. Please is there any possibility to prevent such
unwanted behavior and
to force Chimera that analyses properly protein configuration at each
loaded frame and eventually
changes properly the ribon representation ?
Thank you in advance for any useful advices !
