**Nanotransfer** is a high-performance computational platform for detecting intercellular DNA transfer from single-cell RNA-seq and spatial transcriptomics datasets. Grounded in discovery of physical genomic DNA exchange between human cells (Ly et al., *Cell* 2026), Nanotransfer integrates four orthogonal detection engines with rigorous empirical FDR control to identify cell-to-cell transfer of chromosomal fragments, extrachromosomal DNA (ecDNA), and whole organelle genomes.

## ⚙️ Installation

Install the standard release from PyPI:

```bash
pip install nanotransfer
```

Or install the latest development version directly from GitHub:

```bash
git clone https://github.com/blackbox-genesis/nanotransfer.git
cd nanotransfer
pip install -e .[dev]
```

### Requirements
* Python `>= 3.8`
* `scanpy >= 1.9.0`, `anndata >= 0.8.0`, `numpy >= 1.21.0`, `pandas >= 1.3.0`, `scipy >= 1.7.0`, `scikit-learn >= 1.0.0`
* Optional: `fastapi`, `uvicorn`, `streamlit` for API/Dashboard hosting.

## 🚀 Quickstart

### 1. Python API Pipeline

```python
import scanpy as sc
from nanotransfer import (
    NanotransferPreprocessor,
    GMD,
    SCA,
    ETS,
    ASTD,
    Integrator,
    bh_fdr_control,
)

# Load single-cell AnnData object
adata = sc.read_h5ad("sample_dataset.h5ad")

# Step 1: Preprocessing & Sex-Aware Baseline Setup
prep = NanotransferPreprocessor()
adata = prep.compute_qc_metrics(adata)
adata = prep.filter_cells(adata)
adata = prep.normalize(adata)

# Step 2: Run Multi-Modal Detection Engines
gmd = GMD(z_threshold=2.5, min_region_size=3, sex_aware=True)
adata = gmd.detect(adata)

sca = SCA(k_neighbors=5)
adata = sca.analyze(adata)

ets = ETS(similarity_threshold=0.8)
adata = ets.detect(adata)

# Step 3: Run Multi-Method Integration & FDR Control
integrator = Integrator(min_m=2)
adata = integrator.run(adata)

# Step 4: Apply Benjamini-Hochberg FDR Control (q < 0.05)
adata = bh_fdr_control(adata, alpha=0.05)

print(f"Detected {adata.obs['is_transfer_candidate'].sum()} high-confidence transfer events!")
```

### 2. Publication-Grade Visualization

```python
from nanotransfer.reporting import plot_publication_summary_figure, plot_spatial_contact_network

# Generate 300 DPI Nature-grade vector PDF/SVG summary figure
fig = plot_publication_summary_figure(adata, save_path="nanotransfer_summary.pdf")

# Plot spatial contact network map
fig_net = plot_spatial_contact_network(adata, save_path="spatial_network.png")
```

### 3. Running the Dashboard & REST API

```bash
# Launch interactive Streamlit dashboard
nanotransfer-dashboard

# Or launch FastAPI REST server
uvicorn nanotransfer.api.main:app --host 0.0.0.0 --port 8000
```
