SC-WBD simulated whole-brain corpus — documented subset

Whole-brain simulated trajectories on the 414-parcel anatomical prior, across multiple neural-mass backends.

This repository holds 1 of 151 shards. The complete index is published alongside, so you can see every shard that exists and exactly which ones are here.

Corpus totals (the full corpus, not this subset)

• Trajectories: 37,892
• Trajectory-seconds: 454,704.0
• Shards: 151
• Generated at git 7da6d71fb3dac3c741b0341c64ad1c65a2f59e92-dirty, 2026-08-06T19:38:34Z

Shards per backend:

• jansen_rit: 29
• linear_gaussian: 12
• stuart_landau: 15
• wilson_cowan: 46
• wong_wang: 49

Anatomy it was simulated on

• 414 regions (400 cortex, 14 subcortex, 0 cerebellum)
• density 0.0718, mean tract length 38.76 mm, frame MNI152NLin2009cAsym_RAS

What this is not

• Not measured data. Every trajectory is simulated. It carries the biases of its generative model, not of a brain.
• Not a benchmark with a ground-truth answer key for anything about real neural dynamics.
• The per-shard edges_by_class counts recorded in the index come from a fallback heuristic, not from the anatomical prior's tractography evidence grammar. Use the prior's own evidence array if you need the real edge classes.

Licence and attribution

Computed union: non-commercial: UNKNOWN; share-alike: UNKNOWN; attribution: required; redistribution: unknown; 3 source(s) with UNKNOWN licence (conte69, enigma_hcp_sc, schaefer2018) — unknown is not permissive

• non-commercial: None
• share-alike: None
• sources stating no terms: conte69, enigma_hcp_sc, schaefer2018

These are derived from each source's own licence text by scwbd.release.licence.union_of, not asserted here.

The project

Source code: https://github.com/JacobFV/sc-wbd

The SC-WBD repository itself is licensed CC-BY-NC-SA-4.0, the most restrictive term any of its inputs imposes. Treat that as a floor: the licence section above is computed from this artifact's own inputs and an artifact can inherit more than the floor, never less.

This is research code. It is not a medical device, not a clinical tool, and nothing here should be used to make a decision about a person.

How this card was produced

Every figure above was read at build time from a file in the SC-WBD repository by scwbd/release/publish.py. None of them is typed into the card generator. The sources:

• /data/scwbd/sim_corpus_414/index_fast.json — all corpus totals, shard list and anatomy block
• assets/MANIFEST.json — the anatomical prior's inputs
