Longest Scaffold Length Extractor

Compute Longest Scaffold Length Extractor from explicitly observed positive base lengths; no assembly parsing.

Description

Return the longest supplied positive scaffold length.

The largest observed scaffold length identifies one extreme of a supplied length distribution. It remains distinct from sequence continuity across every scaffold gap.

When to use this tool

Return the longest supplied positive scaffold 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 the maximum 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

The result is a length, not a scaffold sequence or identifier. Gap content, assembly correctness and ties between scaffolds are not examined.
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.
