**Left**, summary plot showing frequency with which the dendrite "in the middle" is ASE (red), AFD (blue), or AWA (yellow) at each position along the amphid bundle. Nose is at the top.

**Center**, population plot showing data for individual animals. Each column represents one animal.

**Right**, color bar showing statistical difference from random dendrite order, expressed as ranked p-values derived from permutation tests. Darker blue represents a greater difference from random.

**Mouse over** the population plot to view the pairwise distances between dendrites and their inferred relative positions in that cross-section. The orientation of the resulting "triangle" in each cross-section is arbitrary.

*Comparison to a random distribution*

At this position, the number of animals with ** _/501**.
