描述----------Description----------
Objects for storing string quality measures.
对象存储字符串质量的措施。
用法----------Usage----------
## Constructors:
PhredQuality(x)
SolexaQuality(x)
参数----------Arguments----------
参数:x
Either a character vector, BString, BStringSet, integer vector, or number vector of error probabilities.
无论是一个特征向量,BString,BStringSet,整数向量,或数字向量的错误概率。
Details
详情----------Details----------
PhredQuality objects store characters that are interpreted as [0 - 99] quality measures by subtracting 33 from their ASCII decimal representation (e.g. ! = 0, " = 1, \# = 2, ...).
PhredQuality对象存储字符解释为[0 - 99]质量的措施,从他们的ASCII十进制表示形式(例如:= 0,“= 1,\#= 2,...!)减去33。
SolexaQuality objects store characters are interpreted as [-5 - 99] quality measures by subtracting 64 from their ASCII decimal representation (e.g. ; = -5, < = -4, = = -3, ...).
SolexaQuality对象存储字符解释为[-5 - 99]质量的措施,从他们的ASCII十进制表示减去64(例如:= -5 <= -4,== -3,...)。
