Ucsc Genome Exploration

UCSC Genome Browser Exploration

Discipline: Genomics | Tools Used: 5 | Servers: 1

Description

Explore genome via UCSC: list genomes, list tracks, get sequence, get track data, and cytoband info.

Tools Used

• list_genomes from ucsc-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/13/Origene-UCSC
• list_tracks from ucsc-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/13/Origene-UCSC
• get_sequence from ucsc-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/13/Origene-UCSC
• get_track_data from ucsc-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/13/Origene-UCSC
• get_cytoband from ucsc-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/13/Origene-UCSC

Workflow

1. List available genomes
2. List tracks for hg38
3. Get DNA sequence for BRCA1 region
4. Get track data
5. Get cytoband info

Test Case

Input

{
    "genome": "hg38",
    "chrom": "chr17",
    "start": 43044295,
    "end": 43125370
}

Expected Steps

1. List available genomes
2. List tracks for hg38
3. Get DNA sequence for BRCA1 region
4. Get track data
5. Get cytoband info

Usage Example

Note: Replace <YOUR_SCP_HUB_API_KEY> with your own SCP Hub API Key. You can obtain one from the SCP Platform.
