Movie S3.

Simulation of a tetramer symmetrizing using our mathematical model. Every cycle of contraction and elastic recoil generates a net push into the cut site. With every cycle, the ephyra relaxes into a new stable configuration where the arms go slightly into the cut site. This continues until spacing between the arms is rebalanced. Matlab codes are available upon request. The movie can also be viewed through the following YouTube link: www.youtube.com/watch?v=VpWf74BkAbE&feature=youtu.be.
