Hi Min Wook, The discrepancy is because you are comparing the probe-level data from an AffyBatch object to the probeset-level data of an ExpressionSet created by gcrma(). Why would you want to convert an AffyBatch object directly into an ExpressionSet object without summarizing the probe-level data into probeset data? The AffyBatch object extends the ExpressionSet structure specifically for probe-level data (individual PM and MM intensities), and typically ExpressionSet objects are reserved for summarized probeset data. For more details on the data classes, use ?"AffyBatch" and ?"ExpressionSet".

Hi Jenny, thanks a lot. I know the relationship between AffyBatch and ExpressionSet. but I wanted to find some pictures about the classes hierarchy for more readable and understandable one. and, why I converted the probe-level data into the probeset data was that I wanted to compare those data by looking directly in excel file. but I can't find how to write the excel file from probe-leve data of the AffyBatch Object. so I tried to do it. and I wanted that it was possible to copy or convert from affybatch object to expression data with some modification directly but without normalization. sincerely Minwook On 8/22/07, Jenny Drnevich <drnevich at="" uiuc.edu=""> wrote: > Hi Min Wook, > > The discrepancy is because you are comparing the probe-level data > from an AffyBatch object to the probeset-level data of an > ExpressionSet created by gcrma().

Min Wook, To my knowledge, unfortunately there is not any such picture. Having a diagram of the classes would be good idea indeed (as it would point developers quickly to existing classes and their relationships)... and may be a also a good exercise to build it automatically from R using introspection and Rgraphviz. > and, why I converted the probe-level data into the probeset data was > that I wanted to compare those data by looking directly in excel file. > but I can't find how to write the excel file from probe-leve data of > the AffyBatch Object. so I tried to do it.

See ?bg.adjust.gcrma for gc-based background correction, ?bg.correct for other bg correction methods, and ?normalize.methods for normalization options. expresso() is nice in that it lets you mix-and-match between a variety of different bg corrections, normalizations and summarization methods, and rma() and gcrma() have arguments to turn off the background correction and/or normalization.
