LOD Score Calculator (linkage analysis)
Two-point linkage LOD scores from recombinant/non-recombinant meioses: θ̂ = r/N, Zmax, LOD at fixed θ, LOD curve table, Morton thresholds (Z≥3 linkage, Z≤−2 excluded). Derived from Morton 1955, Ott 1999, Griffiths, StatPearls. Educational use only.

| Name | Type | Required | Description |
|---|---|---|---|
| thetaMode | select | Yes | Report the maximum LOD at θ̂ = r/N, or evaluate the LOD at a fixed θ. |
| recombinantCount | number | Yes | Number of recombinant meioses observed (r). |
| nonRecombinantCount | number | Yes | Number of non-recombinant meioses observed. |
| theta | number | Yes | Recombination fraction at which to evaluate the LOD in fixed-θ mode (0 < θ < 0.5). |
| decimalPlaces | number |
MCP integration

}List available tools
After connecting to the SSE endpoint, list the exposed tools:
tools/list
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}Call this tool
Invoke the tool by its id, passing arguments built from its parameters:
tools/call
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "lod-score-calculator",
"arguments": {
"thetaMode": "max",
"recombinantCount": 2,
"nonRecombinantCount": 18,
"theta": 0.1,
"decimalPlaces": 4
}
}
}Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
