Hi,All, When I used ReadAffy() to read cel files about 8GB, it return a error: Error: cannot allocate vector of size 2.8 Gb How I can do with it? Thanks -- Best, Changhe Fu [[alternative HTML version deleted]]

An option is to increase the memory available to your R process. If this is not and option, but you have a cluster available, use the package snow and do some parallel computing. http://cran.r-project.org/web/packages/snow/index.html I hope this helps. Daniela [[alternative HTML version deleted]]

Thanks > Hi, Changhe. It looks like you will need to get more memory or use another package such as xps or aroma.affymetrix to deal with your data. You can search the mailing list archives for other suggestions. This is a common problem discussed often. Sean [[alternative HTML version deleted]]
