Hi Joyce,

Usually, NA's comes from higher background the foreground values.  One
way is not to do local background subtraction before performing

say dataraw is a marrayRaw object
dataraw at maGb <- dataraw at maRb <- matrix(0,0,0)
datanorm <- maNorm(dataraw)
write.xls(datanorm at maM, file="Norm.xls")
