Lineage Branch Sibling Order Label Tool

Append an explicit positive sibling index to a lineage parent label without inferring birth order from observations.

Description

Label a supplied one-based child order under a parent identifier.

Developmental measurements depend on specimen identity, staging sources, coordinate registration, image scale and time-zero conventions. A section-area fraction differs from a volume, a generation-number step differs from verified lineage, and a midpoint of observations differs from an exact event time. Local scalar terms do not infer developmental mechanisms.

Label a supplied one-based child order under a parent identifier.

When to use this tool

Use Lineage Branch Sibling Order Label when you already have parentId, siblingOneBased and need to label a supplied one-based child order under a parent identifier.

How to use the tool and how it works

  1. Enter parentId, siblingOneBased. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read label. Use the output convention below.

Require parentId nonempty and siblingOneBased a positive safe integer; return parentId/child-number.1

Limitations and assumptions

  • No lineage is traversed, sibling order inferred, identifier uniqueness established or parent-child relation verified.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Inspect original specimens, calibrated images, acquisition timelines and staging references for biological interpretation. Use complete image, lineage and experimental analyses when needed; local ratios, source-qualified labels and supplied coordinate arithmetic do not perform those analyses.
