     11  * Quality scores are typically represented using a Phred scoring scheme, where read quality = −10 * log10(error)
     12  * For example,
     13    * Quality = 10 => error rate = 10% => base call has 90% confidence
     14    * Quality = 20 => error rate = 1% => base call has 99% confidence
     15    * Quality = 30 => error rate = 0.1% => base call has 99.9% confidence
     16  * See [[http://en.wikipedia.org/wiki/Phred_quality_score|Phred quality score]] for more details.
