Shortest Contig Length Extractor
Compute Shortest Contig Length Extractor from explicitly observed positive base lengths; no assembly parsing.
Description
Return the shortest supplied positive contig length.
The shortest observed contig length identifies one extreme of a supplied length distribution. It can help inspect an input set without reading sequence files.
When to use this tool
Return the shortest supplied positive contig length.
- Prepare the supplied lengths fields for this operation.
- Compare the complete example with the representation used by your own input before carrying the result into another step.
How to use the tool and how it works
- Enter lengths. Use the exact text syntax, units and index conventions explained below.
- Run the tool. If input validation fails, correct the supplied fields before interpreting any result.
- Read result.lengthSummary. Interpret false, null and empty lists using the distinctions below; they can be valid outputs.
Require a nonempty list of positive bounded integer lengths and return its minimum as lengthSummary.1
| Input field | Meaning and representation | Accepted input |
|---|---|---|
| lengths | lengths. | List of finite numbers; bounded by the operation |
| Output field | Interpretation |
|---|---|
| result | Object containing the named outputs below. |
| result.lengthSummary | The length summary value under the stated formula or text convention. |

}Limitations and assumptions
- Despite the tool name, the result is a length rather than the contig sequence or identifier. No filtering, tie listing, assembly verification or completeness assessment is performed.
- Every declared top-level field is required and unexpected fields are rejected. Numeric inputs must be finite; ordinary text fields are bounded to 8,192 UTF-16 code units, with tighter operation-specific limits where stated.
- Ordinary string lists have at most 128 entries of at most 128 code units each; numeric lists and matrices have separate bounded size checks. Nonfinite results and excessively large serialized outputs are rejected.
- Indexes are zero-based and spans have an exclusive end unless explicitly stated otherwise. A valid false, null or empty-list result is distinct from malformed input.
Alternative or Complementary methods
Retain the reference assembly, accession/version and measurement convention with an analysis. Length summaries, flags and lookup notes do not validate an assembly or classify a variant; use the corresponding sequence, alignment or evidence-review workflow.
