Hi, everybody!
I'm in trouble with an R-script to get expression set.
In my final excel-table I get for different probeset an for different samples the same value in an affymetrix experiment.
My script use GCRMA and I have this problem on HGU133plus2 (31 cel files) and on Human Gene1.0 (30 .cel files).
Is this an hardware problem (xp 64 bit 8 gb ram quadcore processor)

thank you in advance

FR
