## 📦 Installation

### Prerequisites
- Python 3.8+
- Docker Desktop
- 8GB RAM (16GB recommended)

### Quick Start

**Windows:**
```powershell
git clone https://huggingface.co/OpenPeerAI/CancerAtHomeV2
cd CancerAtHomeV2
.\setup.ps1
python run.py
```

**Linux/Mac:**
```bash
git clone https://huggingface.co/OpenPeerAI/CancerAtHomeV2
cd CancerAtHomeV2
chmod +x setup.sh
./setup.sh
python run.py
```

Then open: **http://localhost:5000**

## 🚀 Usage

### Web Dashboard
Access the interactive dashboard at http://localhost:5000 with:
- **Dashboard Tab**: Overview statistics and mutation charts
- **Neo4j Visualization**: Interactive graph of cancer relationships
- **BOINC Tasks**: Submit and monitor distributed computing tasks
- **GDC Data**: Browse and download cancer datasets
- **Pipeline Tools**: Run FASTQ QC, BLAST, and variant calling

### GraphQL API

Query cancer data at http://localhost:5000/graphql

**Example: Get mutations in TP53 gene**
```graphql
query {
  mutations(gene: "TP53") {
    mutation_id
    chromosome
    position
    consequence
  }
}
```

**Example: Get patient statistics**
```graphql
query {
  cancerStatistics(cancer_type_id: "BRCA") {
    total_patients
    total_mutations
    avg_mutations_per_patient
  }
}
```

### REST API

**Database Summary:**
```bash
curl http://localhost:5000/api/neo4j/summary
```

**Submit BOINC Task:**
```bash
curl -X POST http://localhost:5000/api/boinc/submit \
  -H "Content-Type: application/json" \
  -d '{"workunit_type": "variant_calling", "input_file": "sample.fastq"}'
```

### Python API

**FASTQ Processing:**
```python
from backend.pipeline import FASTQProcessor

processor = FASTQProcessor()
stats = processor.calculate_statistics("input.fastq")
filtered = processor.quality_filter("input.fastq")
```

**Variant Calling:**
```python
from backend.pipeline import VariantCaller, VariantAnalyzer

caller = VariantCaller()
vcf_file = caller.call_variants("alignment.bam", "reference.fa")
variants = caller.filter_variants(vcf_file)

analyzer = VariantAnalyzer()
cancer_variants = analyzer.identify_cancer_variants(variants)
tmb = analyzer.calculate_mutation_burden(variants)
```

**Neo4j Queries:**
```python
from backend.neo4j import DatabaseManager

db = DatabaseManager()
query = """
MATCH (g:Gene {symbol: 'TP53'})<-[:AFFECTS]-(m:Mutation)
RETURN m.position, m.consequence
"""
results = db.execute_query(query)
db.close()
```

## 📊 Data Model
