[BioC] Importing quantile normalized .txt file to limma for differential expression

[Dhanjit [guest]]

I am using limma package for identifying differential expression of affymetrix .CEL file. I used quantile normalization method and saved the normalized data in .txt file. However, i am not able to import the .txt file into limma for differential expression. 

Kindly tell me the sequential procedure for identifying the differential expression of quantile normalized data.
