Hi All, I have completed back ground correction and normalization of 440 CEL files (Each file has 6.4 million rows). When I tried to extract the raw data from my CEL files I received the following error. I know that this limitation exists in R and C and we cannot have a matrix larger that (2^31) which exceeds memory capacity. Now the question is can we extract that data of chip 1-220 in one object and 221-440 in another object?
The same error is reported when I tried to extract the normalized values. I do not want to summarize data as I need to have access to data of each probe.
