Hi Oliver, With Morph Conformations you can create the morph trajectory so that it includes the forward and backward morphs. For example, instead of aimply morphing 0 -> 1 you can add the same input conformation twice so that you are morphing 0 -> 1 -> 0 (in a single forward playback). I hope this helps, Elaine ----- Elaine C.

Greetings, I like the “Morph Conformations” tool in chimera, and use it a lot (as well as the equivalent tool for maps). In particular, I will often record a movie with the “encode forward then back” option selected, as I find this gives a much better looping animation that is easier to interpret.
When playing the movie from within chimera (In the “MD Movie: Molecular Movement of Morph” dialog”), however, this option is not available - one can loop the animation, but it just jumps back to the start after completion, which can look rather jerky and disjointed, rather than playing forward then back, which I find gives a smoother animation that is better for analyzing the meaning of any conformational change.
Would it be possible to add an alternative checkbox, next to “Loop”, to make this option available? Best, Oliver.
