描述----------Description----------
The two columns of this data set represent the Cy3 (green) absorption intensities for channel 1, and the Cy5 (red) absorption intensities for channel 2 for part of a dye-swap experiment with replicates. They measure expression levels of cellular RNA transcripts assessed in CD4+ T cell lines at different times after infection with HIV-1BRU using DNA microarrays.
这组数据的两列表示通道1,(红色)通道2的Cy5的吸收强度Cy3标记(绿色)吸收强度与复制的染料交换实验的一部分。他们在不同的时间测量与HIV-1BRU的使用DNA芯片后感染单元的RNA转录表达水平评估中CD4 + T单元系。
用法----------Usage----------
data(spotSegTest)
格式----------Format----------
Each column is a vector of intensities of 24 spots arranged in 4 rows and 6 columns, encoded for compact (16-bit TIFF) storage. For processing each column of spotSegTest should first be converted to a 144x199 matrix, then applying the transformation described below.
每一列是一个强度排列成4行6列的24个景点,紧凑编码(16位TIFF)存储向量。为处理每列spotSegTest首先应该被转换到144x199矩阵,然后应用下面描述的转型。

详情----------Details----------
The intensities can be obtained from this data by first subtracting them from 65535 (256*256-1), then squaring, then multiplying by a scale factor 4.71542407E-05. In other words, a number x in the spotSegTest data set
从这个数据可以得到强度,首先减去他们从65535(256 * 256-1),然后现蕾,然后乘以一个比例因子4.71542407E-05。换句话说,数字xspotSegTest数据集
