From: Network organisation and the dynamics of tubules in the endoplasmic reticulum
Tubule contours modelled with Fourier modes. (a) Tangent angles as a function of arclength, calculated directly from the tracked points (solid line) and from the modelled Fourier modes (points) for the tubules in the insets. (b) First 5 Fourier modes used to model the tubules in the single frame depicted in (a). (c) Mode amplitudes of the red tubule in (a) for each tracked frame. (c) Mode amplitudes of the blue tubule in (a) for each tracked frame. Black crosses show mean mode amplitudes.
