[BioC] cannot open file './', reason 'Permission denied' in: file(file, "r")

Dear All,

I get an error message after executing the following commands on RGUI

> library(arrayQuality)
> library(marray)
> TargetInfo<-read.marrayInfo("TargetMSS.txt")
> mraw<-read.Agilent(targets=TargetInfo)


I get the following:

Reading ...  ./RCP6NEW.txt
Reading ...  ./RCP7NEW.txt
Reading ...  ./RCP8NEW.txt
Reading ...  ./
Error in file(file, "r") : unable to open connection
In addition: Warning message:
cannot open file './', reason 'Permission denied' in: file(file, "r")

The working directory is correct and I do have an active internet  
connection. I am not sure why I am getting this warning message. Any  
comments will be appreciated.

Best,

Mete Civelek
