Hi All,

I am working to use AnnBuilder to build a package for a microarray.

I am here just use the small data set from thgu95a in the AnnBuilder as
illustrations of the problems I am facing


When I use my R 2.4.1 in windows,
> myBase <- file.path(.path.package("AnnBuilder"), "data", "thgu95a")
> myBaseType <- "gb"
> mySrcUrls <- getOption("AnnBuilderSourceUrls")
> myDir <- tempdir()
> ABPkgBuilder(baseName = myBase, srcUrl = mySrcUrls, baseMapType =
myBaseType,
+ pkgName = "myPkg", pkgPath = myDir, organism = "Homo sapens", version = "
1.1.0", author = "alex", fromWeb = TRUE)

and I receive the error:

Error in system(paste("gzip -d", fileName), intern = TRUE) :
        gzip not found
Error in unzipFile(fileName, destDir, TRUE) :
        Gzip is either not installed or not in your path.
 You may need to install the Rtools available at:
  http://www.stats.ox.ac.uk/pub/Rtools/


but I already have the Gzip installed in my windows, and it is in the path
already.....


Then I tried to use LInux with R 2.3.1 installed, and I used the same code
as above and I get this error message:

Error in validObject(.Object) : invalid class "GO" object: invalid object
for slot "srcUrl" in class "GO": got class "list", should be or extend class
"character"

However, my object for srcUrl$GO is;

> mySrcUrls$GO
[1] "http://www.godatabase.org/dev/database/archive/latest"


I greatly appreciate if anyone could show me how to solve the problem.
Thanks,

Alex-
