Dear All,

I try to use the mas5 to normalize my data. but it failed. However, I
can use RMA method to normlize the data.

The following is the error message:
Loading required package: affyio
Loading required package: preprocessCore
> raw.data<-ReadAffy();
> mas5.data<-mas5(raw.data);
background correction: mas
PM/MM correction : mas
expression values: mas
background correcting...Error in as.vector(data) : NA/NaN/Inf in
foreign function call (arg 1).

Here is my sessioninfo():
