[BioC] Loess Normalization of Spotted Chip

Hi All,

I am trying to perform loess normalization on spotted oligo chip data 
which have only one channel, instead of two-channel in cDNA data.  I 
would also like to use the print-tip normalization option.  I understand 
I could use the loess normalization function from the "affy" package, 
but I don't believe it takes into account the print-tip.  Does anybody 
has experience in this issue?

thank you
