|
|
| Replay packs (`.rpk`) built with `dmipy_sim`: one converged Monte-Carlo walk each, stored so any acquisition can be replayed on it. Load one with `ReplayPack.load("hf://SubstrateCommons/grey-matter-spheres/<path>")`; the manifest (`manifest.json`) holds the sha256 every load is checked against. This file is rendered from the manifest by `dmipy_sim.replay.publish`. |
