# Cancer@Home v2

A distributed computing platform for cancer genomics research, combining BOINC distributed computing, GDC cancer data analysis, sequence processing (FASTQ/BLAST), and Neo4j graph visualization.

## 🚀 Quick Start (5 minutes)

### Prerequisites
- Python 3.8+
- Docker Desktop
- 8GB RAM minimum

### Installation

1. **Clone and setup**
```bash
cd CancerAtHome2
python -m venv venv
venv\Scripts\activate  # Windows
pip install -r requirements.txt
```

2. **Start Neo4j Database**
```bash
docker-compose up -d
```

3. **Run the application**
```bash
python run.py
```

4. **Open your browser**
- Application: http://localhost:5000
- Neo4j Browser: http://localhost:7474 (username: neo4j, password: cancer123)

## 🎯 Features

### 1. **Distributed Computing (BOINC Integration)**
- Submit cancer research computational tasks
- Monitor distributed workload processing
- Real-time task status tracking

### 2. **GDC Data Integration**
- Download cancer genomics data from GDC Portal
- Support for various cancer types (TCGA, TARGET projects)
- Automatic data parsing and normalization

### 3. **Sequence Analysis Pipeline**
- FASTQ file processing
- BLAST sequence alignment
- Variant calling and annotation

### 4. **Neo4j Graph Database**
- Graph-based cancer data modeling
- Relationships: Gene → Mutation → Patient → Cancer Type
- Interactive graph visualization

### 5. **GraphQL API**
- Query cancer data flexibly
- Filter by gene, mutation, patient cohort
- Aggregate statistics

### 6. **Interactive Dashboard**
- Real-time data visualization
- Network graphs for gene interactions
- Mutation frequency charts
- Patient cohort analysis

## 🧬 Data Flow

1. **Data Ingestion**: Download cancer genomics data from GDC Portal
2. **Processing**: Run FASTQ/BLAST analysis on distributed BOINC network
3. **Storage**: Store results in Neo4j graph database
4. **Visualization**: Query and visualize via web dashboard

## 🔧 Configuration

Edit `config.yml` to customize:
- Neo4j connection settings
- GDC API parameters
- BOINC project URL
- Analysis pipeline options

## 📖 Usage Examples

### Query Mutations by Gene
```graphql
query {
  mutations(gene: "TP53") {
    id
    position
    consequence
    patients {
      cancerType
      stage
    }
  }
}
```

### Submit Analysis Task
```python
from backend.boinc import BOINCClient

client = BOINCClient()
task_id = client.submit_task(
    workunit_type="variant_calling",
    input_file="sample.fastq"
)
```
