Overview of Analyzed Features With Their Variables, Units, and Description (N Indicates Embryos)
| Feature | Variable | Unit | Description |
|---|---|---|---|
| Image height | IN | [µm] | Total height of the image |
| MG height | MGN | [µm] | Radial extension of MG |
| Number/count | NN | Number of objects in ROI | |
| Volume | VN | [µm3] | Volume of object voxel, derived after segmentation |
| Volume coverage | VCN | [%] | Percentage of image volume covered with MG (lowest = 0; highest = 100) |
| Surface | SN | [µm3] | Number of object surface voxels, derived after segmentation (given in [µm3] for comparability between experiments) |
| Surface: Volume ratio | S:VN | Ratio of surface to volume (lowest = 0; highest = 1) | |
| Thickness | TN | Distance from local centerline to the corresponding surface | |
| Skeleton length | LN | [µm] | Skeleton voxels (given in [µm] for comparability between experiments) |
