Figure 5.

The evolution of domains of low nematic ordering are heterogeneous. The images are snapshots where the segmented cells have been coloured according to the value of $\cos 2\theta$ with respect to the channel walls. The times correspond to the elapsed time since the upper-left frame. The data correspond to fast growth (LB) with a mean doubling time of 18 min in a wide slit (60 μm). Two regions of low ordering with respect to the walls (but strong local nematic ordering) are indicated by the solid red oval and dashed white line. The corresponding movie data are provided as electronic supplementary material.
