Hi Lothar, The perframe command does have an “interval” option to do something only at every Nth frame (N >1), but then how to interleave modeldisplay and ~modeldisplay? <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/perframe.html> Here’s a possibly crazy idea, and I really don’t know if it would work: make an alias that hides the model, waits N frames (e.g. 6 frames), and then shows it again. Then use perframe to execute this alias every 2N frames (e.g. 12). I guess it’s worth a try… I hope this helps, Elaine ----- Elaine C.

Hi, in a short animation I would like to turn on/off a second model that is overlapping with the main model. The idea is to show differences by showing/hiding side chains of the second model. I know I can turn off models with ~modeldisp #1 but I don't know how to do that properly in a perframe statement
turn y 2 180 perframe "modeldisp #1 " range 0,1 frames 180 # pseudo code wait
clearly range does not quite work and $1 is presumably not setup to be ~ or nothing. I want to turn #1 on/off say every 6 degrees. How can this be done ?
Thanks, Lothar
