# SpatialAgent — Human Expert Reference Data
Anonymized reference data produced by human scientists for two spatial-transcriptomics
tasks used to benchmark **SpatialAgent**:
1. **Gene panel design** — expert-designed targeted gene panels for the human
**dorsolateral prefrontal cortex (DLPFC / PFC)**.
2. **Cell-type & tissue-niche annotation** — expert annotations of a **developing human
heart** MERFISH dataset (228,633 cells × 238 genes).
All scientist identities are removed. Each task uses its **own independent numbering**, so
the same person generally has a *different* id in the two tasks (this is intentional — the
two studies were anonymized separately). No real names appear anywhere in this repository.
Each expert's methodology is documented (by anonymized id) in the `workflows.csv` files.
## Repository layout
```
panel_design/
workflows.csv # id (1–10) -> free-text description of the panel-design approach
{1..10}.csv # one full panel per expert (ranked gene lists)
split/{id}_top{50,100,150}.csv # top-N subsets of each panel
annotation/
workflows.csv # id (1–8) -> cell-type & niche annotation approach
combined_annotations_anonymized.h5ad # all experts (anonymized) + model/baseline predictions
human_annotations_anonymized.h5ad # human experts only (anonymized), no model columns
per_expert_raw/ # the original per-expert annotation files, anonymized
expert{1,2,5,6,7}.h5ad
expert{3,4}.csv
expert7_niche.h5ad
```
See `panel_design/README.md` and `annotation/README.md` for the column-level details of
each subset.
## Panel design (DLPFC)
10 experts each submitted a ranked panel (typically top 50 / 100 / 150 genes) with a short
rationale per gene. Formats are heterogeneous (experts used different tools), so columns
differ between files; the common fields are a gene symbol, a ranking/priority, and a
free-text reasoning column. `split/` holds the top-50/100/150 truncations used for
size-matched evaluation. Workflows range from purely algorithmic (Persist, greedy kNN
reconstruction) to literature-driven marker curation — see `panel_design/workflows.csv`.
## Annotation (developing human heart, MERFISH)
8 experts annotated the same 228,633 cells. The two combined `.h5ad` objects share an
identical cell index and embeddings:
- `X` — log1p-normalized expression (238 genes); `layers['raw_count']` — raw counts.
- `obsm` — `X_pca`, `X_umap`, `spatial` (tissue coordinates).
- Per-expert columns: `cell_type_tier{1,2,3}_expert{N}`, `tissue_niche_tier{1,2}_expert{N}`,
and consolidated `cell_type_expert{N}` / `tissue_niche_expert{N}`.
- Consensus reference labels: `cell_type`, `tissue_niche`.
`combined_annotations_anonymized.h5ad` additionally contains model / baseline predictions
(`cell_type_agent`, `tissue_niche_agent`, `cell_type_gpt`, `cell_type_sctab`,
`cell_type_popv`, `cell_type_biomni_run_{1,2,3}`, `cell_type_spatialagent_run_4`) for direct
benchmarking; `human_annotations_anonymized.h5ad` is the human-only subset (those columns
dropped). `per_expert_raw/` preserves each expert's original file (with their native,
heterogeneous column schema) for full transparency.
### Caveats
- **annotation expert 1** did not produce tissue-niche labels (niche fields are empty/NA).
- **annotation expert 3**'s labels are of uncertain origin and are likely mis-ordered — use with care.
- **annotation expert 8** has no standalone raw file; their annotations exist only inside the combined objects.
- **panel expert 3** submitted a previously designed panel for the wrong tissue.
