Description
Return signed and absolute gap between sister division times.
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.
Return signed and absolute gap between sister division times.
When to use this tool
Use Cell Division Sister Time Gap when checking an explicit stage, lineage or observation-coordinate convention.
How to use the tool and how it works
- Enter firstDivision, secondDivision. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap, absoluteGap. Use the output convention below.
Return signed and absolute gap between sister division times. signedGap = secondDivision-firstDivision and absoluteGap is its magnitude.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstDivision | First Division | Required. Finite number. |
| secondDivision | Second Division | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |
| absoluteGap | Absolute Gap | Required. Finite number. |

}Limitations and assumptions
- No ordering, matching, clock calibration or developmental interpretation is inferred.
- 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.
