Hi, I am learning microarray data analysis. Are there any tutorials that can analysis microarray data of gpr file format, such as GSM360134.gpr ? I've seen an excelent tutorial at http://bioinformatics.knowledgeblog.org/2011/06/20/analysing-microarray-data-in-bioconductor/, but it is for cel file format.

Thank you for your suggestion!

The limma User Guide has sections on analysis of GenePix gpr files.

Hi! Do you have any pipeline to analyze.gpr files. I am standing right there where you were 3 yrs ago. And limma user guide is not helping either. Do u have any example code to share?

I need assistance with performing RMA normalization on gpr files from microarray data set. The dataset I'm handling comes with gpr files, not the CEL files I anticipated. I've checked the limma manual, yet its method for background correction and normalization seems different than RMA process.

Any advice would be greatly valued.
