The paths travelled by FJ7 macrofibers during production of aggregate structures and pattern formation. Green dots represent starting positions of fibers. Orange dots mark the places to which fibers moved before making contact with another fiber. Blue lines depict the paths taken by walking, pivoting or supercoiling motions on the floor of the Petri dish. Pink lines show the paths taken during dragging motions. The grey blobs show locations and geometry of the final aggregate structures that form the pattern. The maps were produced by analysis of film sequence 3.
