Table 2. Measures for meshes with volumetric (3D) cells.
| Measure | Unit | Description |
|---|---|---|
| Cell atlas | ||
| Cell length (circumferential, radial, longitudinal) | µm | Cell length as determined by 3D Cell Atlas root (shoot rays from the cell center to the side walls to measure cell size along organ-centric directions) |
| Coord (circumferential, radial, longitudinal) | 3D organ coordinates as determined by 3D Cell Atlas root | |
| Geometry | ||
| Cell length (custom, X, Y, Z) | µm | Cell length along the specified direction (cell size is measured as in 3D Cell Atlas root [see above]) |
| Cell wall area | µm2 | Total area of the cell wall |
| Cell volume | µm3 | Volume of the cell |
| Outside wall area | µm2 | Cell wall area that is not shared with another neighboring cell |
| Outside wall area ratio | % | Proportion of cell wall area that is not shared with a neighbor cell |
| Location | ||
| Bezier coord | µm | Associated Bezier coordinate of a cell Requires a Bezier curve or grid |
| Cell coordinate | µm | Cartesian coordinate of a cell |
| Cell distance | µm/cells | Distance to the nearest selected cell (finds the shortest path to a selected cell through the cell connectivity graph, edge weights: Euclidean, cell number or 1/wall area) |
| Distance to Bezier | µm | Euclidean distance to the Bezier curve or grid |
| Mesh distance | µm | Euclidean distance to the nearest vertex in the other mesh |
| Network | ||
| Neighbors | Count | Number of neighbors of a cell |
| Betweenness centrality | - | Computes the betweenness centrality of the cell connectivity graph Edges can be weighted by the length of the shared wall between neighboring cells |
| Betweenness current flow | - | Computes the betweenness current flow of the cell connectivity graph Edges can be weighted by the length of the shared wall between neighboring cells |
