[BioC] vsn + backgroundSubtract

[DAVID ARTETA GARCIA]

Hi Wolfgang and list,

Is it possible to do vsn() or justvsn() with backgroundSubtract=TRUE  
for a one-color genepix chip? I tried and received an error saying  
that "object R was not found". Could I fool the function duplicating G  
and Gb into R and Rb or will the normalisation result then be modified  
and get erroneous output??


Thanks for your help,


David
