描述----------Description----------
Given a read sequence and a list of read quality scores this function returns a (possibly truncated) quality score of the same length as the read.
鉴于只读序列和读取质量分数的名单,这个函数返回读一个相同长度的质量得分(可能被截断)。
用法----------Usage----------
readQualitySample(read, qualities, checkLength = TRUE, ...)
参数----------Arguments----------
参数:read
A sequence read.
读取序列。
参数:qualities
List of sequence read quality scores.
名单顺序读质量分数。
参数:checkLength
Flag indicating whether the length of quality scores should be checked to ensure that they are at least as long as the read. If qualities contains entries shorter than read this has to be TRUE, but see below.
标志,指示是否应检查,以确保他们只要至少读质量分数的长度。如果qualities包含的条目少于read这是TRUE,但是见下文。
参数:...
Further arguments, currently not used.
进一步的论据,目前没有使用。
Details
详情----------Details----------
Using checkLength = TRUE leads to a substantial decrease in performance and is impractical for a large simulation. To avoid this slow down it is recommended to remove short sequences from qualities beforehand so that checkLength = FALSE can be used.
使用checkLength = TRUE导致在性能上的大幅下降,是一个大型模拟不切实际的。为了避免这种缓慢下降,建议从qualities事先让checkLength = FALSE可以用短序列。
值----------Value----------
An read quality score string of the same length as read.
一个阅读的质量得分相同的长度为read字符串。
