描述----------Description----------
Example for list-structure used by many functions in MACAT. It's based on the gene expression data published by Yeoh et al. (2002) The data has been preprocessed using 'vsn' on probe level and the probe values have been summed up to probe set values using the 'median polish' procedure. This is a subset of the data, containing only the data for the 5000 probe sets with the highest variance across the samples and for 10 exemplary samples, 5 from T-lymphocytic Acute Lymphocytic Leukemia (ALL) and 5 from B-lymphocytic ALL.
示例中使用的由麦科特许多功能列表结构。它是基于公布的数据汇等的基因表达。 (2002年)的数据已预处理使用VSN“水平探针和探针值已总结探测使用”位数波兰“程序的设定值。这是数据的一个子集,包含与整个样品和10模范样本,5的T淋巴单元急性淋巴单元白血病(ALL)和5的B-淋巴单元所有的最高差额只有5000探针台的数据。
