Hi, I am trying to check the quality of Human Exon 1.0 ST arrays before and after normalization. I am using the HuEx-1_0-st- v2,coreR3,A20071112,EP.cdf file. When I use: raw <- extractMatrix (csBC,verbose=verbose), I have got the following error messg:
20090421 16:31:08|Getting data for the array set... 20090421 16:31:08| Allocating matrix... Error in matrix(naValue, nrow = ncells, ncol = nbrOfArrays) : cannot allocate vector of length 825753600 20090421 16:31:08| Allocating matrix...done 20090421 16:31:08|Getting data for the array set...done It seems that I don't have enough memory (I am using macpro with 4GB RAM). Is there any alternate ways to compare probe intensity values before and after normalization? BTW, where can I find the documentation of function: extractMatrix? Thanks in advance.
