# Epigenomic Landscape Mapping

**Discipline**: Epigenomics | **Tools Used**: 4 | **Servers**: 2

## Description

Map epigenomic landscape: overlapping features, regulatory elements, binding matrices, and phenotype links.

## Tools Used

- **`get_overlap_region`** from `ensembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl`
- **`get_phenotype_region`** from `ensembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl`
- **`get_species_binding_matrix`** from `ensembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl`
- **`get_track_data`** from `ucsc-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/13/Origene-UCSC`

## Workflow

1. Get overlapping regulatory features
2. Get phenotype associations in region
3. Get binding matrix data
4. Get UCSC epigenomic track data

## Test Case

### Input
```json
{
    "region": "17:43044295-43125370",
    "species": "homo_sapiens",
    "genome": "hg38"
}
```

### Expected Steps
1. Get overlapping regulatory features
2. Get phenotype associations in region
3. Get binding matrix data
4. Get UCSC epigenomic track data

## Usage Example

> **Note:** Replace `sk-b04409a1-b32b-4511-9aeb-22980abdc05c` with your own SCP Hub API Key. You can obtain one from the [SCP Platform](https://scphub.intern-ai.org.cn).
