WebbSimpleaffy does not know the QC parameters for this array type. > See the package vignette for details about how to specify QC parameters manually This above line is the hint you seem to have missed. There is no set of QC parameters for this particular chip, so you have to create some yourself. Webb8 nov. 2024 · Affymetrix recommend a series of QC metrics that should be used to check that arrays have hybridised correctly and that sample quality is acceptable. These are … WebbAffy芯片数据预处理,一般分为三个步骤 1.背景处理(background adjustment) 2.归一化处理(normalization) 3.汇总(Summarization) normalization 可以选择mas5,rma,gcrma等方法,一般后两个比较常用。 可以根据自己的数据集情况自行选择。 基因芯片数据处理当中不同分析方法比较 ,在这里选用rma方法。 phone call on tablet
