| file | what |
|---|---|
| `DiSCo_mask.nii.gz` | the 40³ mask of the phantom's voxels (the tracking domain) |
| `DiSCo_ROIs.nii.gz` | the sixteen end regions, labels 1 to 16 (seeds and connectome endpoints) |
| `DiSCo_gradients.bvals`, `DiSCo_gradients_dipy.bvecs` | the dataset's 364-measurement gradient table (b in s/mm²), the "DiSCo 364" acquisition |
| `DiSCo_Connectivity_Matrix_Strands_Count.txt` | ground truth: strands per region pair |
| `DiSCo_Connectivity_Matrix_Cross-Sectional_Area.txt` | ground truth: total cross-sectional area per region pair |
| `DiSCo_Strands_Diameters.txt` (the centrelines, `DiSCo_Strands_Trajectories.tck`, are read from `SubstrateCommons/disco-replay` `substrate/` at the pinned revision) | the 12,196 strands' centerlines (in units of the 25 µm voxel, i.e. the image grid) and inner diameters (mm): the ground-truth view |
