# PhredUtils

#### object PhredUtils extends Serializable

Helper singleton for converting Phred scores to/from probabilities.

As a reminder, given an error probability \epsilon, the Phred score q is:

q = -10 log_{10} \epsilon

10. #### def errorProbabilityToPhred(p: Double): Int

    p

      An error probability to convert to phred.

    returns

      The input probability as a phred score, rounded to the nearest int.

15. #### def logProbabilityToPhred(p: Float): Int

    p

      A log-scaled success probability to conver to phred.

    returns

      Returns this probability as a Phred score. If the log value is 0.0, we clip the phred score to 256.

19. #### def phredToErrorProbability(phred: Int): Double

    phred

      The phred score to convert.

    returns

      The input phred score as an error probability. If the phred score is above 255, we clip to 255.

20. #### def phredToLogProbability(phred: Int): Float

    phred

      The phred score to convert.

    returns

      The input phred score as a log success probability.

21. #### def phredToSuccessProbability(phred: Int): Double

    phred

      The phred score to convert.

    returns

      The input phred score as a success probability. If the phred score is above 255, we clip to 255.

22. #### def successProbabilityToPhred(p: Double): Int

    p

      A success probability to convert to phred.

    returns

      One minus the input probability as a phred score, rounded to the nearest int.
