MacDonald" <jmacdon@uw.edu> Hi Jim, Thank your reply. As far as I know, affy is not very suitable for MoGene-1_st-v1 chip (I do not validate, but get the information from internet). Actually I am analyzing a large number of MoGene-1_st-v1 microarrays. I found that aroma.affymetrix and RMAExpress may be suitable for large scale data. I contacted Benjamin Bolstad about RMAExpress. It really donnot expenditure much computer memory, with a faster speed than aroma.affymetrix package. Good luck Wei Liu [[alternative HTML version deleted]]
