Hi Stanley,

If you had taken the time to do a couple of searches, you would have found:

a.) The makecdfenv/affy pipeline doesn't handle exon arrays.
b.) The error you see is because you don't have enough memory.

To do any exon analysis you could use makePlatformDesign/oligo, xps or 
exonmap. Two of which will likely require a machine with more RAM than 
you currently have. You might be able to get by using xps.
