Hi All,
For a while I have been using these lines below to normalize a large
Affy
data set with customCDFs and gcrma. I can't seem to make it work
anymore.
For some reason, in the affinity adjustment of gcrma, there is a
switch to
the affy CDF which gives an error later. Its a bit puzzling. I am
confident
the cdf name is correct and I even updated the custom CDFs to version
14. I
am running R 2.12 and bioconductor 2.7 on a Mac.
Can anyone suggest a solution to this?
Thanks,
Yair
#This is my code
library(affy)
library(gcrma)
options(pkgType="source")
filenames<-as.character(read.table("../CEL-FileNames3.txt",
header=FALSE)[,1
])
eset <- just.gcrma(filenames, cdfname="hgu133plus2hsentrezg",
optimize.by=
"memory")
data<-as.matrix(exprs(eset))
save(data,file="/tmp/gcrma.normalized.Rbin")
This is the error
