译者：生物统计家园网 机器人LoveR
描述----------Description----------
Function that will remove probes from ProbeLevelSet if they have more than one match in a given genome.
函数将从ProbeLevelSet删除探针，如果他们有一个以上的在一个特定的基因组的比赛。
用法----------Usage----------
excludeDoubleMatchingProbes(object, genome="BSgenome.Hsapiens.UCSC.hg18", verbose=TRUE,
directions=c("matchForwardSense", "matchForwardAntisense", "matchReverseSense", "matchReverseAntisense"),
previousData = NULL)
参数----------Arguments----------
参数：object
A ProbeLevelSet class object.
ProbeLevelSet类对象。
参数：genome
character string with the name of the BSGenome in which sequences should be found. Defaults to the human genome.
字符串名称序列中应BSGenome。人类基因组的默认值。
参数：verbose
TRUE or FALSE.
TRUE或FALSE。
参数：directions
character string with elements from c("matchForwardSense", "matchForwardAntisense", "matchReverseSense", "matchReverseAntisense"). Defines which directions (complementary and reverse mirrorings) that should be scanned. Defaults to all directions.
从C元素的字符串（“matchForwardSense”，的“matchForwardAntisense”，“matchReverseSense”，“matchReverseAntisense”）。定义应扫描方向（互补性和反向mirrorings的）。四面八方的默认。
参数：previousData
Optional: The output from a call to findSequenceInGenome. If given the scanning will be skipped, and the probes will be omitted directly. Useful in cases were datasets from the same region needs to be processed.
可选：调用到findSequenceInGenome从输出。如果给定的扫描将被跳过，探测器将直接省略。有用的情况下，来自同一区域的需要处理的数据集。
Details
详情----------Details----------
This function will take quite a while to run, so if you have many sequences, overnight runs are recommended. BSgenome contains some alternative versions of chromosomes. They are marked with an underscore. This function automatically disregards chromosome names with an underscore, and this is known to work for the human genome. Nevertheless, check the output printed to terminal if all chromosomes are included. The function is a wrapper around findSequenceInGenome, which can be used for purposes that are more flexible (although that function really is just following the example in the BSgenome package)
此功能将需要相当一段时间运行，所以如果你有很多序列，通宵运行。 BSgenome染色体包含一些替代版本。他们用下划线标记。此功能会自动无视染色体名以下划线，这是已知的人类基因组工作。然而，如果包括所有的染色体都打印到终端的输出。该函数是一个围绕findSequenceInGenome的包装，它可以更加灵活的用途使用（虽然这功能真的只是在BSgenome包的例子）
At present, there is no functionality to check matches with known SNP or known splice forms taken into account.
目前，没有任何功能检查与已知的SNP或已知的剪接形成考虑到比赛。
值----------Value----------
The ProbeLevelSet class object provided as argument, with all double matching probes removed. Double matching probes are probes whose sequence are found twice or more in the genome. In addition, the output of the matching investigation is saved in the notes of the ProbeLevelSet and can be further examined for information on the locations of the probe sequences in relation to the BSgenome sequences.
提供ProbeLevelSet类对象作为参数，所有双匹配拆除探针。双匹配探针探针的序列基因组中发现过两次或两次以上。此外，输出匹配的调查，被保存在票据ProbeLevelSet关系BSgenome序列的探针序列的位置信息可以进一步检查。
