Hello,
I am new to Bioconductor. I have read four of my .gpr files using the
read.GenePix() method of marray package. Now I want to subtract the
background from foreground of the Cy5 values and calculate the global
median normalization on the subtracted values. I don't know how to
find the subtracted values for Cy5 values. Any help is greatly
appreciated. If you could show how this could be done using swirl
dataset, that will be great.
I tried RGsubbed<-backgroundCorrect(dat.scat.cy5, method =
BGsubmethod, verbose = FALSE) but I am getting Error in
backgroundCorrect(dat.scat.cy5, method = BGsubmethod, verbose = FALSE)
:
object 'BGsubmethod' not found
I have loaded marray and limma libraries. dat.scat.cy5 is my marray
object where I read the .gpr files.
Thanks
