  I am trying to find a way to reanalyse this, but is struggling to find 
a appropriate way. I just want to know whether the genes in this array 
are below or above the detection level threshold  used in beadarray.
 Has anybody got any advice about a way to  analyse microarray data 
deposited in GEO to get this kind of information?
many thanks
Nat
