hi members,

is there any function or easy way to get the gene level of a human exon 
affymetrix chip? currently i calculate the average of all exonic 
probeset intensities for genes of interest individually.

other question what i have is there any easy way to remove poor 
performing probesets via DABG (detection above background score)?

many thanks and best regards
