# valency-anndata

Experimental tooling to support notebook analysis of polislike data.

:sparkles: Inspired by [scanpy][] and the [scverse][] ecosystem! :heart:

## Installation

```
pip install valency-anndata
```

## Usage

### Loading Polis Data

```py
import valency_anndata as val

adata = val.datasets.polis.load("https://pol.is/report/r29kkytnipymd3exbynkd")
val.viz.schematic_diagram(adata, diff_from=None)
```

### Running Polis Pipelines

```py
with val.viz.schematic_diagram(diff_from=adata):
    val.tools.recipe_polis(adata, key_added_pca="X_pca_polis")
```

```py
val.viz.embedding(adata, basis="pca_polis", color="kmeans_polis")
```

### Exploring Polis Pipelines

```py
val.viz.schematic_diagram(diff_from=adata):
    val.preprocessing.calculate_qc_metrics(pacmap_adata, inplace=True)
```

```py
val.viz.embedding(adata, basis="pca_polis",
    color=["kmeans_polis", "pct_seen", "pct_agree", "pct_pass"],
)
```

### Running & Exploring Alternative Pipelines

```py
from valency_anndata.tools._polis import _zero_mask, _cluster_mask

with val.viz.schematic_diagram(diff_from=adata):
    _zero_mask(adata)
    val.preprocessing.impute(
        adata,
        strategy="mean",
        source_layer="X_masked",
        target_layer="X_masked_imputed_mean",
    )
    val.tools.pacmap(
        adata,
        key_added="X_pacmap",
        layer="X_masked_imputed_mean",
    )
    _cluster_mask(adata)
    val.tools.kmeans(
        adata,
        k_bounds=(2, 9),
        use_rep="X_pacmap",
        mask_obs="cluster_mask",
        key_added="kmeans_pacmap",
    )

### AI-Assisted Exploration (Claude Code Skill)

This repo includes a [Claude Code skill](./.claude/skills/valency-anndata/) that guides you through loading and exploring Polis conversations interactively. It will prompt you for which projections and annotations to visualize, then run the full pipeline for you.
