Description
Check which disjoint candidate root side contains all supplied outgroup tips.
Evolutionary summaries depend on sampled sequences/populations, reference states, ploidy, time units and stochastic assumptions. A mixture expectation differs from a drift simulation, and a callable-allele denominator differs from an individual count. Labels and local tree conditions do not reconstruct ancestry or establish a biological mechanism.
Check which disjoint candidate root side contains all supplied outgroup tips.
When to use this tool
Use Out Group Root Side Flag when checking the stated evolutionary record, reference, expectation or scale convention.
How to use the tool and how it works
- Enter outgroupTipIds, firstSideTipIds, secondSideTipIds. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read allOnFirst, allOnSecond, splitAcrossSides. Inspect allOnFirst, allOnSecond, splitAcrossSides before interpreting the associated values.
Require unique nonempty outgroup ID list, disjoint first/second side lists and every outgroup ID in one side. Return all-on-first, all-on-second or split-across-sides flags.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| outgroupTipIds | Outgroup Tip Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| firstSideTipIds | First Side Tip Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| secondSideTipIds | Second Side Tip Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| allOnFirst | All On First | Required. Boolean. |
| allOnSecond | All On Second | Required. Boolean. |
| splitAcrossSides | True when the supplied unique outgroup tips occupy both disjoint supplied side lists. | Required. Boolean. |

}Limitations and assumptions
- Side membership is supplied; no actual tree, outgroup monophyly, suitable root or biological relationship is 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.
Alternative or Complementary methods
Use verified samples/references and appropriate complete phylogenetic, population-genetic or statistical models for actual biological inference and uncertainty.
