Hi Xiang,

Try with 
> dd=read.AgilentFE(targets$FileName,makePLOT=TRUE)

If that does not work , try with "path" attribute.

Then the above command becomes,
> dd <- read.AgilentFE(targets$FileName,makePLOT=TRUE, path="path to the FE files")

I hope you are familiar with path naming in different OS.

Regards,
Prashantha

hi, there:

> targets = read.targets("1.txt")
> data(targets)
> targets
       FileName Treatment GErep Subject Array
Ast     Ast.txt        st     1       A     1
Bst     Bst.txt        st     1       B     1
Aunst Aunst.txt      unst     2       A     1
Bunst Bunst.txt      unst     2       B     1

THEN, when I use this function:

> dd=read.AgilentFE(targets,makePLOT=TRUE)

ERROR MESSAGE is :

Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") : cannot open file 'Ast.txt': No such file or directory

is there anybody know what's wrong with my work?

Thanks in advance,

Xiang
