Hi guys, I just tried to do some analysis with my new array data. I followed the A biologists guide to using Bioconductor by Chris Bye. But I got the error message when I used widget.marrayRaw(). The following is the screen shot: > widget.marrayRaw() Loading required package: tcltk Loading required package: tkWidgets > getwd() [1] "E:/EcoliArray/Test_Oct2003" > widget.marrayRaw() Finish creating a new marrayLayout: mytest.layout Finish creating a new marrayInfo: mytest.target Finish creating a new marrayInfo: mytest.genes Error in readLines(con, n, ok) : `con' is not a connection > This worked for me before. I just don't know what's going on this time? Any suggestion? Thanks a lot for your help, Ying Chen [[alternative HTML version deleted]]
