createTargetsFile()所属R语言包:beadarray
A function to generate a targets file given a directory of Illumina bead-level files
函数生成一个目标文件中给出了Illumina的珠级文件目录
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This function, when pointed to a directory containing Illumina bead-level files (e.g. txt, idat, locs, tif) will return a simple targets file of the sort expected by beadarray. Note that a user created targets file is likely to be of greater value.
此功能时指出,含珠Illumina的文件(如TXT,IDAT,LOCS,TIF)目录将返回一个简单预期由beadarray排序目标文件。请注意,一个用户创建的目标文件很可能是更大的价值。
用法----------Usage----------
createTargetsFile(dir = NULL, nochannels = 1, channel1 = "Grn", channel2 = "Red", txtsuff = "txt", imgsuff = "tif", locssuff = "locs", xmlsuff = "xml", verbose = FALSE, special = c("sdf", "fiducial"), ColourConfusionStop = T, metricsflag = "Metrics", metsep = "\t", metricsection = "Section", metricchip = "Matrix")
参数----------Arguments----------
参数:dir
dir: The directory containing the Illumina bead-level files. By default, will search the working directory.
dir:含有Illumina的珠级文件目录。默认情况下,将搜索工作目录。
参数:nochannels
nochannels: Does the directory contain 1 or 2 channel arrays? Setting this argument to be null will result in the function making its best guess.
nochannels:目录是否包含1或2通道阵列?设置此参数为空,将导致功能作出最好的猜测。
参数:channel1
channel1: The string indicating that files are associated with the first channel (usually Grn).
channel1:字符串表示,相关文件与第一通道(通常GRN)。
参数:channel2
channel2: The string indicating that files are associated with the second channel (usually Red).
channel2:表示第二通道(通常红色)相关文件的字符串。
参数:txtsuff
txtsuff: The suffix of files containing the bead-level intensities (usually txt, but occasionally csv).
txtsuff:含珠级强度的文件后缀(通常为TXT,但偶尔CSV)。
参数:imgsuff
imgsuff: The suffix of files containing the images.
imgsuff:包含图像的文件后缀。
参数:locssuff
locssuff: The suffix of files containing the precise bead locations (usually locs).
locssuff:包含的确切位置(通常是LOCS)珠文件的后缀。
参数:xmlsuff
xmlsuff: The suffix of files containing the meta-data (usually xml).
xmlsuff:包含元数据(通常是XML)的文件后缀。
参数:verbose
verbose: Determines whether or not the function reports on its progress as it goes along.
verbose:确定是否功能报告其进展,因为它伴随。
参数:special
special: Files with names containing special words (such as fiducial) are ignored.
special:含有特殊字词的名称(如基准)的文件将被忽略。
参数:ColourConfusionStop
ColourConfusionStop: This determines the behaviour of the function if there is a discrepancy between the number of channels specified, and the number apparently present.
ColourConfusionStop:这决定了功能的行为,如果有一个指定的通道数之间的差异,而且这个数字显然目前。
参数:metricsflag
codemetricsflag: This gives the key word that can be used to identify metrics files.
codemetricsflag:这给出了关键的字,可用于识别指标文件。
参数:metsep
metsep: This gives the cell separator used in the metrics file.
metsep:这给人的指标文件中使用的单元分离机。
参数:metricsection
metricsection: This gives the column heading used in the metrics file to indicate array section names.
metricsection:这使列的指标文件中的标题用来表示数组的节名。
参数:metricchip
metricchip: This gives the column heading used in the metrics file to indicate the chip name.
metricchip:这使列标题中的指标文件用来指示芯片的名称。
