描述----------Description----------
Given raw bead level data, in the form of .txt and .locs file, this function combines the two producing a new file with the data stored in a compressed format.
鉴于原珠级别的数据，在形式。TXT。LOCS文件，这个功能相结合的两个生产与新的文件压缩格式存储的数据。
用法----------Usage----------
compressBeadData(txtFile, locsGrn, locsRed = NULL, outputFile = NULL,
path = NULL, nBytes = 8, base2 = TRUE, fullLocsIndex = FALSE,
nrow = NULL, ncol = NULL, progressBar = TRUE)
参数----------Arguments----------
参数：txtFile
The name of the .txt file to be read in.
要读入的。txt文件的名称
参数：locsGrn
The locs file for the green channel.
绿色通道的的LOCS文件。
参数：locsRed
The locs file for the red channel. Only needed for two channel data.
对红色通道的的LOCS文件。只需要两个通道的数据。
参数：outputFile
Name of the file to be created.
要创建的文件名。
参数：path
Path to where the input files can be found. If NULL the current working directory is used. This is also the directory where the output files will be written.
到哪里可以找到输入文件的路径。如果为NULL，当前的工作目录。这也将被写入输出文件的目录。
参数：nBytes
Gives the number of bytes that are used to store the fractional parts of the bead coordinates. For a single channel array the maximum value is 4, whilst it is 8 for a two channel array. Any number larger than this is automatically set the the maximum value. If the maximum value is used the coordinates are stored in the .bab file as single precision floating point numbers, as they are in the .locs files. If a value smaller than the maximum is choosen then the integer parts of each coordinate are stored seperately. The requested number of bytes are then used to store the fractional parts, with a corresponding loss of precision as the number of bytes decreases.
给出了用来存储珠坐标的小数部分的字节数。为一个单一的通道阵列的最高值是4，而它是双通道阵列。任何比这更大的数量是自动设置的最大值。如果使用最大值的坐标存储。BAB文件为单精度浮点数，因为他们。LOCS文件。如果值小于最大choosen然后每个坐标的整数部分分开存放。请求的字节数，然后用来存储小数部分，字节跌幅相应的精度损失。
参数：base2
If not using the full precision coordinates, the approximations can be stored as either a binary or decimal fraction. Using a binary fraction (base2 = TRUE) provides a greater accuracy, but can lead to a meandering number of decimal places in the reconstructed .txt files. If one wants a consistent number of decimal places, set base2 = FALSE.
如果不使用完整的精确坐标，可以存储为二进制或小数近似。使用一个二进制数（基类2 = TRUE），提供了一个更大的准确性，但可能会导致蜿蜒重建。txt文件数量的小数位数。如果一个人想一致的小数位数的号码，设置基类2 = FALSE，。
参数：fullLocsIndex
Default value of 0 uses a linear model fitted to each segment of the array to allow reconstruct the locs file when the file is decompressed. Using a value of 1 a simple index is used to record the locs file order, but requires more space.
默认值为0，使用线性模型拟合的阵列允许重建LOCS文件解压缩文件时的每个部分。使用值1，一个简单的指数是用来记录LOCS文件的顺序，但需要更多的空间。
参数：ncol
This specifies the number of columns in each grid segment on the array and, if left blank, can normally be infered from the grid coordinates. However, this can fail for particularly small grids. If one wants or needs to specify them explicitly, these values can be found in the .sdf which accompanies the bead level output from the scanner. The number of columns per segment can be found within the tag <SizeGridX>
这指定阵列上的每个格段的列数，如果留空，通常可以从网格坐标的推导。然而，这可能失败，特别是小网格。如果想要或需要明确指定他们可以发现，这些值。自卫队，伴随着从扫描仪的珠电平输出。每段的列数，可以发现在标签<SizeGridX>
参数：nrow
See ncol. If needed can be found within the <SizeGridY> tag in the .sdf file.
看到NCOL。如果需要，可以发现内。sdf文件<SizeGridY>标签。
参数：progressBar
By default the function uses a txtProgressBar to indicate progress through the compression. Setting this argument to FALSE supresses the drawing of this progress bar.
默认情况下，该函数使用一个txtProgressBar表明通过压缩进度。这个参数设置为FALSE supresses这个进度栏的图纸。
Details
详情----------Details----------
In the future the file names will be determined automatically, rather than requiring manual entry of each. The path argument may also be amended so there are seperate options for the locations of the input and output files.
文件名，在未来将被自动确定，而不是要求每个手工录入。路径参数，也可能被修订，有单独的输入和输出文件的位置选择。
值----------Value----------
Primarily invoked for its side effect, which is to produce a compressed version of the input files. The function returns, invisibly, the total number of beads stored in the compressed file.
主要调用它的副作用，这是产生输入文件的压缩版本。函数返回，无形之中，珠总数存储在压缩文件。
