Description
Compare two supplied sibling cell-cycle durations.
Developmental stages and lineages can be represented by labels, ordered events and observation intervals. Index and time differences preserve a declared representation but do not discover lineage, assign stage or establish biological equivalence.
Compare two supplied sibling cell-cycle durations.
When to use this tool
Use Cell Division Timing Sibling Gap when checking an explicit stage, lineage or observation-coordinate convention.
How to use the tool and how it works
- Enter firstBirth, firstDivision, secondBirth, secondDivision. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read firstCycle, secondCycle, cycleGap. Use the output convention below.
Compare two supplied sibling cell-cycle durations. Require each division >= its birth; return the two elapsed cycles and cycleGap = second-first.1

| secondBirth | Second Birth | Required. Finite number. |
| secondDivision | Second Division | Required. Finite number. |
| Output field | Interpretation | Returned shape |

| firstCycle | First Cycle | Required. Finite number. |
| secondCycle | Second Cycle | Required. Finite number. |
| cycleGap | Cycle Gap | Required. Finite number. |

}Limitations and assumptions
- Times must share units; sibling identity, clock accuracy and biological significance are not established.
- 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
Review the original biological evidence and its staging or lineage model before drawing mechanistic conclusions.
