Hi, everyone,

I ran the test case in "Introduction to the Bioconductor

marrayInput package first. When I ran the session in (read.marrayRaw) I got the following error messages. Other sessions work well.

The functions and errors are labled with blue and red respectively.

>mraw <- read.Spot(path = datadir, layout = galinfo$layout, gnames = galinfo$gnames, target = swirlTargets)

Error in file(con, "r") : unable to open connection

In addition: Warning message: 

cannot open file `C:/PROGRA~1/R/rw1091/library/marray/swirldata/81'

> fnames <- as.vector(swirlTargets@maInfo[,1])

> swirl.raw <- read.marrayRaw(fnames, path = datadir,

+ name.Gf = "Gmean", name.Gb = "morphG",

+ name.Rf = "Rmean", name.Rb = "morphR",

+ layout = swirl.layout,

+ gnames = swirl.gnames,

+ targets = swirlTargets)

Error in file(con, "r") : unable to open connection

In addition: Warning message: 

cannot open file `C:/PROGRA~1/R/rw1091/library/marray/swirldata/81' 

> array1.raw <- read.Spot(fnames, path=datadir)

Error in file(con, "r") : unable to open connection

In addition: Warning messawell

cannot open file `C:/PROGRA~1/R/rw1091/library/marray/swirldata/81'

I copy and paste the whole set of examples. 

Is it possible something is not right with the spot files?

I really need your help to solve this problem.

Thank you very much!!

Best regards
