Dear Mark, I'm new to microarray data analysis but have a strong background in Biology. I inherited a gene expression log2-transformed dataset produced in Illumina (FinalReport_AVGSignal) and I was able to import it and quantile- normalize it in Partek. As I have relatively few samples, I think that I should do the analysis with Limma rather than t-test and ANOVA implemented in Partek. Is there a simple way for me to import the normalized "FinalReport_AVGSignal" file into beadarray, so that I can run Limma in it?
