Description
Apply a supplied mutant-count increment at fixed population.
Computational biology distinguishes discrete counts, probabilistic weights, sequence indexes and logical rules. A supplied event or record flag can be summarized without simulating a stochastic process, validating a sequence annotation or establishing a biological mechanism.
Apply a supplied mutant-count increment at fixed population.
When to use this tool
Use Neutral Model Mutant Frequency Step when checking the stated count, sequence, Boolean-rule or support convention.
How to use the tool and how it works
- Enter mutants, population, deltaMutants. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nextMutants, beforeFrequency, afterFrequency. Use the output convention below.
Apply a supplied mutant-count increment at fixed population. Require positive whole population, mutants within it and the incremented count still in bounds; return nextMutants and frequencies before/after.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| mutants | Mutants | Required. Safe integer; minimum 0. |
| population | Population | Required. Safe integer; minimum 1. |
| deltaMutants | Delta Mutants | Required. Safe integer. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nextMutants | Next Mutants | Required. Safe integer. |
| beforeFrequency | Before Frequency | Required. Finite number. |
| afterFrequency | After Frequency | Required. Finite number. |

}Limitations and assumptions
- The increment is supplied rather than sampled; no neutral transition probability or evolutionary trajectory is calculated.
- 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
Use the complete sequence, identifier universe or stochastic/logical model for actual inference, sampling and uncertainty analysis.
